The highest level of respiratory protection required when there is a high risk of inhaling hazardous substances, but a lower level of skin protection is sufficient.

This level of protection is required when the type and concentration of hazardous substances in the air are known and a specific type of respirator can be used.

The minimum level of personal protective equipment (PPE) required.

This is the area where there is actual or potential contamination and the highest risk of exposure to hazardous substances.

These zones are designed to clarify the type of work happening in each area, the dangers present at different locations, and which areas should be avoided by unauthorized or unprotected personnel.

These zones specify both the degree of hazard at different locations within the spill and the type of operations allowed in each zone.

A small pump that maintains pressure in a fire sprinkler system, ensuring a constant supply for fire suppression.

Photoelectric smoke detectors use light to detect smoke. Smoke particles either block light (less light) or scatter it (more light), triggering the alarm.

Ionization smoke detectors use a radioactive source to create a small electric current in the air. Smoke particles reduce the flow of electricity, triggering the alarm.

Flame detectors use either ultraviolet or infrared light to respond to fire. They are particularly useful for systems requiring a fast response.

Combustible gas indicators measure the presence of flammable gases by detecting changes in the resistance of a heated element. Resistance increases when in contact with the gases.

In long, narrow containers like pipes, the pressure can increase dramatically, up to 20 times the initial pressure, potentially reaching 15-20 atmospheres.

A dust explosion occurs when a cloud of airborne dust particles ignites within an enclosed space. This happens if there's enough dust, oxygen, and a source of ignition.

A BLEVE happens when a container holding a liquid above its boiling point ruptures. The liquid rapidly vaporizes, causing a violent expansion.

An explosion in a pressure vessel containing nonreactive materials occurs when the vessel, with a weak structure, fails under low pressure. While not as violent as a BLEVE, it can still cause significant damage.

An unconfined vapor cloud explosion happens when a flammable gas or vapor is dispersed in the open air and ignites. The explosion's intensity depends on the size and concentration of the cloud.

A deflagration of mists occurs when a fuel dispersed as a fog or mist ignites within flammable limits. This can result in a powerful and rapid combustion.

A chemical reactor runaway happens when a chemical reaction becomes uncontrolled, leading to a rapid increase in pressure and temperature inside the reactor.

A nuclear reactor accident can cause a significant release of energy, creating a powerful pressure wave or blast wave that can cause damage and injury.

Firewalls are vertical barriers that prevent the spread of fire within a building or between buildings by containing the flames within a designated area.

Special storerooms are designed to safely store flammable liquids, with features like explosion-proof electrical fixtures, ventilation, self-closing doors, and grounding systems.

Storage cabinets, located outside or inside special storerooms, protect stored liquids from fires, confine spills, and keep flammables organized.

Drums are containers for flammable liquids with safety features. They must be closed, have approved valves that close automatically, and be stored properly.

Safety cans are designed to hold small quantities of flammable liquids. They are self-closing, have pressure relief valves for vapor release, and include flame arrestors to prevent flames from spreading.

Plunger cans are used to apply flammable liquids to cleaning cloths or wipes. They are designed to minimize exposure and control liquid application.

Cleaning and dip tanks require specific fire protection features, including controlled ventilation, flame-resistant materials, and proper containment systems.

Pyrophoric materials ignite spontaneously in air at low temperatures or within a short time after exposure to air. Examples include certain metals, fireworks, and flares.

Hypergolic materials ignite spontaneously upon mixing, even without a source of ignition. Examples include rocket fuels like hydrazine and N2O4.

A system used to categorize fire hazards of materials using a 0-4 rating scale for health, flammability, reactivity, and special hazards.

The NFPA 704 System uses a scale from 0 to 4, where 0 indicates no hazard and 4 indicates the most severe hazard.

Extinguisher markings should be durable and visible from 3 feet away. If using a pictograph marking system, the decal should be visible from the front. The locations of extinguishers should be marked with a red rectangle painted above them and the signs identifying extinguisher locations should not be obstructed.

Sprinkler systems designed for use in residences, considering limited water supply. Their primary purpose is life safety, aiding in evacuation.

These detectors respond to a predetermined rate of rise in air temperature, typically around 12°F per minute.

These detectors have a bimetallic element that bends and closes a circuit when the temperature rises. Some use a fusible spring-loaded element that melts at a specific temperature, closing the circuit.

Detectors that respond to a fixed predetermined temperature in the surrounding air, without considering the rate of rise.

Pneumatic detectors are mechanical devices ideal for locations where electricity use must be avoided due to explosivity. They work based on changes in air pressure inside a bulb due to temperature increases.

These devices are thermal detectors that work based on an increase in air pressure inside a bulb due to an increase in temperature.

These detectors have a bimetallic element with two metals that have different coefficients of expansion. When the temperature rises, the element bends and closes a circuit.
