What is a Fire Suppression System?

A fire suppression system is a collection of devices and equipment meant to identify, manage, or put out fires either manually or mechanically. Depending on the suppression agent being employed, these systems are frequently divided into the following categories:

  • Water-Based Systems: Fire suppression sprinklers that emit water.
  • Foam systems: These systems are useful for putting out fires started by combustible liquids.
  • CO2 Systems: These systems push out oxygen to extinguish fire, making them perfect for places with electrical equipment.
  • Dry Chemical Systems: Perfect for high-hazard locations, these systems use dry powders to put out fire.

Key Benefits

  • Less Property Damage: Prevents fire from spreading.
  • Life Safety: Quickly extinguishes fire to protect residents.
  • Legal compliance: Lowers legal hazards and adheres to fire safety laws.

Fire Suppression System Installation Procedure

Proper planning, specialized design, and detailed testing are required in the installation of a fire suppression system. The process outline is provided below:

The Importance of Fire NOC for Building

Fire NOC is a document issued by the local fire safety authority after inspecting a building. It certifies that the building meets all necessary fire safety regulations and follows all prescribed fire safety standards and regulations.

The fire NOC verifies that a building is equipped with all fire safety products including fire extinguishers, alarms, sprinklers, smoke detectors, etc. It is mandatory for every type of building such as schools, hospitals, theaters, malls, etc.

Obtaining a fire NOC makes sure that you follow all regulatory compliance and is often required for getting approval for various types of buildings.

What is a fire NOC?

As mentioned earlier, a fire NOC for building is a legal document issued by the fire department to endorse that the building has met all the necessary safety standards. It ensures the safety of occupants by verifying the implementation of fire prevention measures in the building.

Submitting an application for a fire NOC along with the required documents is crucial for obtaining one. Building plans and layouts, construction details, ownership and authorization documents, fire safety system details, compliance certificates, application forms, and site photographs are required for receiving a fire NOC.

Importance of a fire NOC for buildings

Safety assurance

A fire NOC for a building guarantees that it complies with the fire safety regulations set by the local fire department. You have to set up fire safety systems such as extinguishers, alarms, and sprinklers along with emergency exits for acquiring a fire NOC.

Also, the fire NOC plays an important role in preventing fire hazards and ensuring occupant safety. The inspection conducted by the fire department to issue NOC helps you identify and eliminate risk, prepare for emergencies, and reduce casualties and property damage.

Regulatory compliance

Complying with local fire safety regulations is crucial to ensuring the safety of occupants. This reduces fire risks and prepares you for emergency situations by equipping yourself with fire prevention and control systems. These safety measures help to build the trust of employees and customers.

Legal consequences of operating without a fire NOC include fines and penalties, operational risks, legal actions, reputational damage and even the immediate shutdown of operations. More than a regulatory requirement, a fire NOC is a step towards ensuring a safe and legally compliant environment.

Insurance and financial implications

A fire NOC is mandatory to receive insurance claims smoothly without any delay if any fire incident takes place. Insurance companies require a fire NOC to process the claim. Otherwise there are high chances of the insurance claim getting rejected. The fire NOC shows that the owner has taken necessary safety measures to reduce liability and thereby claim insurance. Buildings with a fire NOC are considered prone to fire incidents, leading to reduced insurance premiums.

Fire NOC has several financial benefits including reduced damage costs, avoidance of fines, etc. Effective fire prevention systems minimize property damage during fire accidents and compliance with safety norms eliminates fines for not following safety measures. Regular maintenance of fire safety systems, as demanded by the Fire NOC, prevents costly repairs or replacements.

Building occupancy approval

A fire NOC is mandatory for obtaining occupancy and operational permits for any building. It ensures that the building complies with fire safety standards, keeping people and assets safe. Fire NOC assures that the building is equipped with fire prevention, detection, and control systems. It also serves as proof that the building adheres to fire safety laws. Fire NOC is issued only to buildings that have emergency exits or fire escape routes. Many businesses get approval only if they possess a fire NOC certificate.  

 

Applications for fire NOC are essential for all types of buildings including residential, public, commercial, institutional, etc. It is to testify that a building complies with the safety regulations. Obtaining a fire NOC for buildings has many benefits such as safety assurance, regulatory compliance, insurance and financial implications, and building occupancy approval. Overall, a fire NOC ensures safety, compliance, and operational efficiency.

Types Of Fire NOC

A fire NOC (No Objection Certificate), also known as a Fire Safety Certificate is a document issued by the local fire department or the regulatory authority. It stands as a testament that a building or facility has met all the fire safety standards and regulations set forth by authorities.

Before issuing the certificate, the fire department inspects the area to make sure that it complies with specific fire safety criteria. These criteria include the presence of fire safety products among other necessary safety measures.

 Why are fire NOCs important?

Fire NOCs are important because they ensure the safety of the people in a building at the time of a fire. The NOC certifies that the building has complied with the necessary fire resistant features such as fire alarms, fire extinguishers, emergency evacuation plans etc. Fire NOCs are critical not only for the safety of occupants but also for obtaining approvals for construction, occupancy, and business operations.

Fire NOCs based on building and usage

Each type of building requires different types of fire NOC. Let’s discuss them.

Residential fire NOC

Residential buildings such as apartments require a fire NOC to ensure compliance with fire safety regulations. A fire NOC is required during the construction phase or before occupancy to ensure that the building is safe.

Fire exits and staircases, smoke detectors and alarms, firefighting equipment, emergency lighting etc consist of the safety standards required for residential buildings.

Commercial fire NOC

Fire NOC for commercial buildings such as offices and malls is to ensure compliance with fire safety regulations and to create a safe environment for employees and visitors. This ensures that the building is equipped with fire detection and prevention systems to handle emergency situations effectively.

Fire detection and alarm systems, sprinkler systems, fire extinguishers, emergency exits, evacuation plans etc are the fire safety measures required for commercial properties.

Industrial fire NOC

Industrial facilities have specific fire safety requirements due to the presence of high-risk elements such as flammable materials and hazardous chemicals. The chance of fire-related accidents is very high.

Flammable substances, overloaded circuits, chemical hazards, heat generating equipment, limited emergency exists etc are the reasons for common fire hazards in industrial setups. NOCs can address these hazards by ensuring proper storage facilities, regular maintenance of electrical systems, heat-resistant materials etc.

Institutional Fire NOC

Institutions such as schools and colleges, hospitals and healthcare centres require an institutional fire NOC before starting work. These institutions must ensure the safety of students, teachers, doctors, and patients by providing a fire safety environment with proper evacuation plans and fire-resistant construction.

Additional safety considerations in these institutional settings include fire resistant doors and walls, conducting regular fire drills, automatic alarms, sprinkle systems and backup power systems.

Fire NOCs based on facility requirements

Based on facility requirements, fire NOC types are two – temporary and permanent.

Temporary fire NOC

A temporary fire NOC is required for short term programmes such as exhibitions, public events, construction sites etc, where fire safety is a concern. There will be large crowds and therefore it is essential to ensure their safety through fire management measures.

In order to obtain a temporary fire NOC, you have to submit an application to the local fire department along with the relevant documents. The fire department officials inspect the site and if the site adheres to the safety standards, then the NOC is issued after you pay the required fee.   

Permanent fire NOC

A permanent fire NOC is issued for long-term establishments such as residential complexes, commercial and institutional buildings, and industrial facilities. It certifies that a building complies with safety standards. Permanent NOCs are issued for the long-term to ensure legal compliance and occupant safety.

Even though a permanent NOC is issued for long-term use, periodic renewals are required to maintain it. After the inspection of the fire department, you have to submit the updated documents and an application for renewal. A renewed certificate will be issued after verification.

Fire NOC categories based on fire hazard level

The degree of fire NOC varies based on fire hazard level and they can be categorized into three.

Low-risk fire NOC

A low risk fire NOC applies to buildings that have less chance of fire hazards. It is due to the types of operations taking place and the materials used. Small residential buildings, offices, educational institutions, warehouses for non-flammable goods and health clinics are the buildings and facilities that fall under low-risk.

Requirements for a low-risk NOC include basic fire safety equipment, building with features such as minimum two fire escapes, ventilation facilities, water supply, proper evacuation plan etc. 

Moderate-risk fire NOC

A moderate-risk fire NOC is required for industries and commercial spaces with moderate fire hazards. It is due to high occupancy levels and the complexity of operations used. Medium-sized manufacturing companies, commercial buildings such as malls, offices, restaurants, health and educational institutions with capacity above the low-risk category fall under moderate-risk.

Fire safety equipment, buildings with fire resistant walls, ceilings and multiple fire exits, safe storage practices for flammable materials etc are required for a moderate-risk fire NOC.

High-risk fire NOC

A high-risk fire NOC is mandatory for industries and facilities with substantial fire hazards. It is due to the high complexity of operations, materials handled, or occupancy density. Industries and setups with high fire hazards include chemical and petrochemical plants, heavy manufacturing industries and large commercial and residential complexes.

Specific safety protocols include fire protection systems, fire detection and alarm systems, emergency exit and evacuation plans, ventilation and smoke control. Inspection and approval processes include preliminary risk assessment, fire department review and on-site inspection before the NOC is issued.

 

NOCs are critical documents issued by fire departments to certify that a building or facility complies with fire safety standards. There are different types of fire NOC and they vary based on building, facility requirements and fire hazard level. NOC’s are important to ensure the safety of lives and property and for legal compliance. Compliance with fire safety standards demonstrates a commitment to safety and responsibility, which builds trust among people.

Types of Fire Extinguishers & Their Uses

Fire safety is crucial regardless of the setting, be it at the workplace, at home, or in an industrial setting. The fire can start abruptly and the damage they cause could be devastating if they are not dealt with promptly. It is important to choose the right type of fire extinguisher. It can make the difference between an incident that is minor or an ensuing fire. This blog aims to describe the type of fire extinguishers for fire currently in use along with their unique functions. This information will help you choose the most appropriate extinguisher for your requirements and prevent a flame from escalating.

Why Fire Extinguishers Are Essential



Fires can be caused by a variety of various hazards. Every type of environment, whether industrial or residential, is prone to particular fire risks. In these scenarios fire extinguishers serve as the first line of defence. Extinguishers can be a fantastic method to prevent small fires from growing. Fire safety services in Kerala stress the importance of having the correct extinguishers available as part of a comprehensive safety program.
Furthermore the building codes mandate that residential and commercial structures include fire protection equipment like fire extinguishers. Apart from placing lives and property at risk, failing to comply with the law can be punished with legal consequences.


Types of Fire Extinguishers & Their Uses


There are five kinds of fire extinguishers. They include dry powder (DCP) as well as wet chemicals. To ensure that your home is conforming to the requirements it is essential to put the right fire extinguisher in the proper place. The fire risk is determined by the kind of fuel used to create a fire in a particular location.


1. Water extinguishers Class A Fires



Extinguishers using regular water can be used to extinguish the flames that are caused by materials that ignite. They can be found in a variety of places, like storage and warehouses. The dimensions range from 6L, 9L, 45L and 60L. The water extinguishers possess cooling properties that decrease the temperature and keep the spread of fire. Extinguishers for water are white with an inscription that reads “Water”. Water extinguishers must be marked with a symbol that reads ‘Water Extinguisher.’



Uses:
Fire extinguishers made of water are common because they are considered to be ‘traditional fire extinguishers’. However the current guidelines usually recommend foam extinguishers because they are capable of extinguishing both classes A and B flames.

However, they’re beneficial for locations that have an abundance of combustible material for example, storage facilities, warehouses or paper mills. They also serve as textile factories.

Along with CO2 extinguishers, they are also effective in the home. The categories that are most likely to be associated with fire are therefore covered. 

Don’t use water-based fire extinguishers to:

 

  • Electric fires can result in electrocution
  • Cooking fires, for example the chip pan (Class F-type fires)
  • Inflammable gas fires, such as butane and methane (Class C-type fires)
  • Incidents involving flammable liquids like paint and petrol (Class B flames)

 

2. Foam fire extinguishers

 

Foam extinguishers are also known by the name of AFFF foam extinguishers for fires are typically used to  fight fires that are class A (solids) and class B (liquids). They come in 2L, 3L and 9L capacities, though 6 litres are the most commonly used.

It is possible to identify them with the use of a cream-coloured tag on the body that reads “Foam”. Additionally, an ID label is recommended to be placed in their vicinity with the words “Foam Extinguisher’.

Foam fire extinguishers function by two methods. First, they’re water-based which reduces the temperatures of fire. The second is that they put out the flames using their aqueous film which forms foam (AFFF) that smothers the flame, stopping it from sparking again. The foam can be utilized on liquids that contain flammable substances since it acts as an insulating layer between the substance and flames.

Foam fire extinguishers are great for locations that have multiple fire hazards for example, hotels, offices garages, factories and other buildings. The majority of buildings will benefit by having an extinguisher for fire.


What can foam fire extinguishers be used to do?

  • The fires that involve flammable solids such as wood and paper, as well as the textile industry (Class Fires)
  • Incidents that involve flammable liquids like diesel, petrol paint, and other flammable liquids (Class A fires)

Don’t use foam fire extinguishers to:

  • Cooking fires made of grease and oil (Class F Fires)
  • Incidents involving flammable gas (Class C-type fires)

 

3. CO2 fire extinguishers

 

CO2 extinguishers for fires (also called carbon dioxide extinguishers) are mostly used to extinguish electrical fires. They are recommended to be coupled with foam fire extinguishers.

CO2 fire extinguishers are identified with a black tag that says CO2. They feature a distinct black nozzle. They should also be identified by an ID tag that reads CO2 extinguisher..

CO2 fire extinguishers emit carbon dioxide. The gas remains in the form of a liquid, and changes into a gas once released. Since the gas is released quickly, the fire extinguishers are not recommended to be used in conjunction with fires that involve cooking oil since they could cause the fire to spread.

CO2 fire extinguishers cannot reduce fires, but they substitute oxygen with carbon dioxide, which removes the fuel. Because of this, they’re extremely effective in electrical fires. CO2 fire extinguishers can be advised for places where there is a huge number of electrical equipment, such as schools, offices and hospitals, where they must be used in conjunction with foam fire extinguishers. CO2 fire extinguishers can be found in 2kg, 4.5kg, 6.5kg, 9kg, and 22.5kg sizes.

 

What can CO2 fire extinguishers be employed to do?

  • The fires can be caused by equipment like generators and all electrical equipment (electrical fires)
  • The fires that are caused by volatile liquids, including diesel, petrol, or paint (‘class B fires)

Do not use CO2 extinguishers to:

  • Incidents that are caused by grease and oil (Class F Fires).

 

4. MAP Extinguishers (Class A, B, C) or Dry Powder

Usage
MAP extinguishers are also known as ABC powder-type fire extinguishers These are multi-functional and can be utilized on fires involving solid substances (Class A) and liquids that are flammable (Class B) as well as gas (Class C). The powder acts by stopping the chemical reaction that is occurring in the fire.

Not Suitable for

These extinguishers are not appropriate for use in tight areas, since the powder may create breathing difficulties. In addition, the powder could make a mess and obstruct vision while fighting fires.


Wet Chemical Fire Extinguishers (Class F/K)


Usage: Wet chemical extinguishers are designed specifically for kitchen fires that contain cooking oils and fats like those used in deep fat fryers (Class F). The extinguisher releases a chemical that cools the flames. It also creates a soapy layer on top of the oil burning, which prevents ignition.

Not Suitable for: These extinguishers are not suitable for electrical fires or those with flammable liquids, such as gasoline or gas.

Conclusion

Knowing the types of fire extinguishers and their proper use is crucial to maintaining the safety of your workplace or home. A properly functioning extinguisher can stop small fires from becoming out of control. Make sure you check your property for the proper fire safety equipment and then maintain it regularly to ensure that it’s in good working order.

Fire breaks out in Bandra high-rise, no casualties

Mumbai: In yet another incident of a fire in a high-rise building in Mumbai, a level 2 blaze erupted on the 14th floor of the ground plus the 21-storey Jivesh building on Bandstand Road in Bandra at 7.

Mumbai: In yet another incident of a fire in a high-rise building in Mumbai, a level 2 blaze erupted on the 14th floor of the ground plus the 21-storey Jivesh building on Bandstand Road in Bandra at 7.46 pm. No casualties were reported.

Mumbai Fire Brigade (MFB) rushed 16 fire engines and jumbo tankers to the spot. Fire fighting operations were carried out using a turntable ladder from the external side of the building, fire brigade officials said. The cooling operation was ongoing till late at night.

Hemant Parab, Chief Fire Officer (CFO), said that the firefighting system in the high-rise was defunct. “The firefighting system was not working and all residents have been evacuated safely. We are carrying out a detailed investigation and depending on its outcome we will send them a notice,” Parab said.

During cooling operations, 31-year-old firefighter Kaushal Rajput received minor injuries.

A senior fire official who was present at the spot said that some repair work was being carried out between the 13th and 14th floors where the blaze erupted. “The actual reason is yet to be ascertained. We have shut down the electricity lines as a precautionary measure and all the residents have been evacuated and are currently sheltered in the basement of the building,” a senior fire department official said.

The residents vacated the building right soon after the fire broke out so no one needed to be rescued. In addition to the fire brigade officials, Mumbai police, ambulances and ward staff were also present at the site.

Mumbai: Fire brigade likely to issue notice to Bandra building over ‘non-functional’ firefighting equipment

A fire broke out at the 14th floor of the 21-storey building in Bandra west.

The Mumbai Fire Brigade is likely to issue a notice to Jivesh Terraces in Bandra west for “non-functional” firefighting systems at the building. The decision came after a fire broke out at the 14th floor of the 21-storey building and the firemen discovered that the firefighting equipment was non-functional. While no resident was injured, one fireman received minor injuries due to suffocation.

“Since the firefighting system was non-functional, we will issue a notice to the building under the Maharashtra Fire Prevention Act. If the firefighting system would have been working, the flames could have been doused much earlier,” said an official from the fire brigade.

The fire department is conducting an investigation to find out the exact cause of the fire which broke out around 7.45 pm and was doused at 10 pm. Officials added that prima facie it appears that the fire started due to a short circuit in the air-conditioning unit of the flat. The power supply of the building will also be restored.

Many residents had assembled at the upper floors of the building and were later rescued safely. More than 20 residents were evacuated from the building.

Navi Mumbai Fire: 1 body found, 1 still missing

Fire officials said that while the major blaze is under control, some of the portions are still catching small fires which are being doused.

NAVI MUMBAI: Around 12 hours after a fire broke out in Khairane MIDC (Maharashtra Industrial Development Corporation), one casualty has been reported, while another person is still missing, fire officials said on Saturday.

While the major blaze is under control, some of the portions are still catching small fires which are being doused. “In the areas wherein the fire is doused, we are conducting cooling procedure. After reaching the terrace of the West Coast Polychem Pvt Ltd on Saturday morning, we found the first body who was later identified as NS Nair. There were no burn injuries on him. He is suspected to have died of suffocation. One person is still missing and we are looking for him,” NMMC fire officer Purushottam Jadhav said.

Nikhil Sanjay Pashilkar (26), a resident of Kalyan is the second person who is still missing. Nair, who is above 60 years of age was also a resident of Kalyan.

The fire call was made at Rabale MIDC Fire station at around 3.17pm on Friday and the first company to catch fire was that of west Coast Polychem Pvt Ltd which later spread to Hind Elastomers. One of the eyewitnesses Amita Shah on Friday said that many female labourers who were sleeping on the terrace of the West Coast Company after their shift had managed to come down somehow during the fire incident safely. “While some seemed suffocated, some were vomiting. They were too traumatised and taken to hospitals,” Shah said.

“The biggest problem in MIDC area is of lack of safety. Even the marginal spaces available between the two companies is used for dumping drums and it becomes a challenge for us to work and douse the fire,” fire officer RB Patil from MIDC said.

 

Fire at Mumbai airport’s cargo complex

Mumbai Fire Brigade chief officer Hemant Parab said, “Our vehicles from the Mumbai fire brigade quickly and doused the fire. There was a monsoon shed put on the terrace and this caught fire.’’

A tarpaulin shed at a cargo complex inside Chhatrapati Shivaji International Airport caught fire on Monday noon. The Mumbai Fire Brigade and the fire services department of the Mumbai airport quickly responded to the emergency and doused the blaze.

The Director General of Civil Aviation, Arun Kumar, said he was informed that the fire was restricted to the cargo complex area.

Mumbai Fire Brigade chief officer Hemant Parab said, “Our vehicles from the Mumbai fire brigade quickly and doused the fire. There was a monsoon shed put on the terrace and this caught fire.’’

The Mumbai Fire Brigade sent three fire trucks and two jumbo tankers, and the fire was completely doused by 12.59 pm.

Car on Fire, Pune-Mumbai Expressway- 7 Passesngers Manage to Escape

28 May 2022 : In a miraculous escape, seven
female passengers of a car that caught fire at
Borghat on Pune-Mumbai expressway, managed

to stay unhurt, police officials said on Saturday.
According to police, the women hailed from
Vichumbe village near Panvel and were heading
to Ekvira Mata Mandir on Friday, when the
incident took place. The other family members
were there in another car, which was ahead of
them.

According to the highway police, the driver saw
smoke coming out of the cars bonnet and alerted
the passengers. All the occupants got down and
moved to a safe distance from the car, which
caught fire and was reduced to ashes within no
time. An elderly women too was helped to alight
and was brought out safely.

The Lonavla police have ordered a probe into the
fire incident. Police Inspector Sitaram Dubal
said, “It was a Nissan Tereno and all the
passengers are unhurt. We will investigate the
case further.”

Unique Fire Safety Challenges of Tall Buildings

Two other considerations for high-rise fire
safety include exterior wall assemblies and
performance-based fire resistance. Exterior
wall assemblies that include combustible materials
are another fire protection issue that is being
discussed in the media and fire safety community.
These exterior wall assemblies are popular as they
provide the opportunity to make a building iconic
and aesthetically pleasing. Additionally, these
assemblies improve energy efficiency and reduce
water and air infiltration.

Even with these benefits, they have their
shortcomings. In recent years, significant damage
has resulted from rapid and extensive fire spread
over the length of the building's facade either
externally or internally through the insulation
cavity. The investigations into the cause of these
fires have revealed that wall assemblies that contain
combustible materials were a contributing factor to
the rapid fire spread in these incidents.

For example, media reports and social media videos
of tall building fires in the United Arab Emirates
(UAE) as recently as March 2016 at the Ajman One
Tower and on New Year's Eve (2015) at the Address
Downtown Dubai Hotel have shown the world how
fire can quickly spread up multiple levels of a high-
rise building that has exterior wall assemblies
containing combustible materials.

Examples of exterior wall assemblies that contain
combustible materials include exterior insulation
finish systems (EIFS), metal composite material
(MCM) claddings, high-pressure laminates, foam
plastic in cavity walls, and water-resistive barriers
(WRB). In regards to fire safety, the combustibility of
the assembly's components impacts its fire hazard.
For example, the foam insulation that is part of EIFS
and MCM assemblies is combustible and
propagates rapid flame spread when exposed to fire.




Common fire spread scenarios include fire spread
up a wall, either via the outside surface or through
concealed spaces within the wall. Additionally, in
the fire events cited earlier, fire spread into the
interior floor areas was controlled by the sprinklers
that were installed in the interior of the building.
However, the sprinklers could not control the fire
from spreading up the building's exterior.

Currently, there are several test standards that
evaluate exterior, non-load-bearing wall assemblies
that include combustible components. In the
United States, the most prevalent test method is
outlined in NFPA 285, Standard Fire Test Method
for Evaluation of Fire Propagation Characteristics of
Exterior Non-Load-Bearing Wall Assemblies
Containing Combustible Components. Other
standards are available in Canada (CAN/ULC S-
134), United Kingdom (BS 8414) and internationally
(ISO 13785).

Moving forward, complying with one of the
applicable test standards is an important step in
reducing the risk that an exterior fire will spread up
multiple levels in a tall building. At the same time,
passing a test procedure does not preclude
designers and engineers from taking other steps to
ensure that adequate life safety is provided
throughout a tall building.

Performance-Based Fire Resistance

The consequences of partial or global collapse of tall
buildings due to a severe fire pose a significant risk
to occupants and the fire service. Tall buildings
often have unique design features whose role in the
structure and fire response are not easily
understood using traditional fire protection
methods. These unique factors may warrant a need
to adopt an advanced structural fire
engineering analysis to demonstrate that the
building's performance objectives are met.
Performance - based design of structural fire
resistance entails three steps: (1) determination of
the thermal boundary conditions to a structure
resulting from a fire; (2) calculation of the thermal
response of the structure to the fire exposure, and
(3) determination of the structural response of the
structure. Guidance on performing this type of
analysis can be found in the SFPE Engineering
Standard on Calculating Fire Exposures to
Structures, and SFPE Engineering Standard on
Calculation Methods to Predict the Thermal
Performance of Structural and Fire Resistive
Assemblies.
