Exit doors

Where exit doors open directly onto any street, alley or other area where vehicles may be operated, there must be adequate barriers and warnings provided to prevent employees fiom stepping into the path of traffic. Doors that swing in both directions and are located between rooms where there is frequent traffic, are to be provided with viewing panels in each door. 

Exit stairways that are required to be separated from other parts of a building are to be enclosed by at least 2-hour fire-resistive construction in buildings more 

The outcome of mishandling explosives is disastrous and a very unforgiving process. Mistakes by individual who have been specially trained in the use and handling of explosive are not acceptable and usually end in deaths. 

All explosives shall be kept in approved magazines. Stored packages of ejqrlosives are to be laid flat with top side up. Black powder, when stored in magazines with other explosives, is to be stored separately. 

Workplace fires and explosions kill 200 and injure more than 5,000 workers each year. In 1995, more than 75,000 workplace fires cost businesses more than 2.3 billion. Fires wreak havoc among workers and their families and destroy thousands of businesses each year, putting people out of work and severely impacting their livelihoods. The human and financial toll underscores the serious nature of workplace fires.

Small loads are commonly processed in a box furnace. The product is placed on the furnace hearth through a door. Box furnaces may be single-ended or double-ended. A single-ended box furnace is usually used in an air atmosphere appHcation where the product can be removed hot from the furnace for cooling. A double-ended box furnace is usually used in a controlled atmosphere appHcation. In this case a water cooler is attached to one end. The product can be placed on the hearth (in the heat chamber) through the front door, then after the product reaches temperature, it is manually transferred into the water cooler for cooling before it is manually removed out the exit door on the other end of the water cooler.

Where practical routes between exit points should be defined by lines painted on the floor or facility pavement in reflective oil resistant paint. All exit doors should be plainly marked. Direction arrows and wordings should be positioned along escape routes where necessary to guide personnel to exit points or the perimeter of the facility. The arrows should be preferably self illuminating (i.e., luminescent). 

Entry and exit doors should be fitted so that no more than 1/8 to 1/4-in. spaces are at the top, bottom, and sides of the door. This should exclude rodents from entering. Insects and dust can enter very small openings. Nylon...

During an emergency the personnel should be able to access portable lamps and torches. These should be located adjacent to exit doors, in operational rooms, plant rooms, emergency accommodation areas, OlM s offices, central control room and muster areas. They should be provided with charger units and be suitable for zone 1 hazardous areas, and be capable of operating for at least five hours.

Consumer units - Recent fire statistics have shown that a large number of domestic fires involved plastic consumer units as a source of the fire. Consumer units are often located at the entrance or exit door or under stairs, raising the possibility that a fire starting as a result of faulty wiring could spread to coats or other household items and block the emergency escape routes. Regulation 421.1.200 now requires that consumer units be manufactured from non-combustible material, for example metal, or be enclosed in a non-combustible enclosure. Consumer units and switchgear must comply with BS EN 61439-3. 

An emergency exit door used for evacuation in a confined location such as in an aircraft, boat, or submarine. Usually considered a secondary means of evacuation to be used when the normal egress facility is unavailable. 

The portion of an exit route that is generally separated from other areas to provide a protected way of travel to the exit discharge from the effects of an incident. An example of an exit is a 2-hour fire-resistance-rated enclosed stairway that leads from the fifth floor of an office building to the outside of the building. Exits include exterior exit doors, exit passageways, horizontal exits, and separated exit stairs or ramps. See also Fire Escape. 

The allowable maximum number of individuals that are allowed to occupy a structure. Maximum occupancy postings are primarily provided at structures to ensure that the available exits for the facility are adequate and panic will not ensue during an emergency evacuation. The maximum occupancy postings are based on measurable standards for exit door provisions. These provisions are most commonly cited in the National Fire Protection Association (NFPA) 101, Life Safety Code (LSC). See also Overcrowding. Maximum Permissible Concentration (MPC)... 

Perimeter fences that block sidewalks must contain adequate signs directing pedestrian traffic to a safe walkway. Place primary signs on the perimeter fence. However, use other signs to conununicate other safety-related information to pedestrians. Inform contractors to keep all corridors and exit doors clear at aU times. Keep all external exit ways, walks, and drives free from debris, material, tools, and vehicles. Contractors mnst conduct all safety training and education of their employees. Many healthcare organizations may reqnire some construction workers to attend facility-conducted sessions. 

In order to leave a building you must know where the exits are Fire codes require that exit signs be clearly marked so finding an exit should be easy. Exit signs are typically located well above eye level near exit doors and stairwells, but it is possible, under heavy fire conditions, that smoke will obscure these signs. This discussion assumes that you are making a choice to leave the building far sooner than when heavy smoke conditions develop. 

Larger pieces of equipment, such as a 5-L Dewar flask or a safety shield, might temporarily be placed on the floor, perhaps even near an exit door (Figure 5.3.6.5). These can become trip hazards and might impede rapid exit during an emergency. 

Many workers in the factory jumped from the ninth floor to their deaths rather than burn alive. The factory fire exit doors were locked, and the doors that were not locked only opened inwards and were effectively held shut by the onrush of workers trying to escape the blaze. Tlie only safety measures available for the wakers were 27 buckets of water. As the clothing materials fed the fire, workers tried to escape anyway they could.
