Guidelines for Job Hazard Analysis – Draft 4/18/2008Hazard Hazard DescriptionsChemical(Toxic)

A chemical that exposes a person by absorption through the skin, inhalation, or through the blood stream that causes illness, disease, or death. The amount of chemical exposure is critical in determining hazardous effects. Check Material Safety Data Sheets (MSDS), and/or OSHA 1910.1000 for chemical hazard information.

Chemical(Flammable)

A chemical that, when exposed to a heat ignition source, results in combustion. Typically, the lower a chemical’s flash point and boiling point, the more flammable the chemical. Check MSDS for flammability information.

Chemical(Corrosive)

A chemical that, when it comes into contact with skin, metal, or other materials, damages thematerials. Acids and bases are examples of corrosives.

Explosion(chemical reaction)

Self explanatory.

Explosion(Over gas/energy due to a significant pressure differencePressurization)

Sudden and violent release of a large amount of such as rupture in a boiler or compressed gas cylinder.

Electrical(Shock/ is incorrectly or inadvertently grounded, such as Short Circuit)

Contact with exposed conductors or a device that when a metal ladder comes into contact with power lines. 60Hz alternating current (common house current) is very dangerous because it can stop the heart.

Electrical(Fire)

Use of electrical power that results in electrical overheating or arcing to the point of combustion or ignition of flammables, or electrical component damage.

Electrical(Static/ESD)

The moving or rubbing of wool, nylon, other synthetic fibers, and even flowing liquids can generate static electricity. This creates an excess or deficiency of electrons on the surface of material that discharges (spark) to the ground resulting in the ignition of flammables or damage to electronics or the body’s nervous system.

Electrical(Loss of Power)

Safety-critical equipment failure as a result of loss of power.

Electrical(Arc blast/Flash)

An arc flash occurs when powerful, high-amperage currents travel, or arc, through the air. This can occur when high voltage differences exist across a gap between conductors. The result is an instant release of tremendous amounts of energy. Temperatures as high as 36,000°F have been recorded in arc flashes. The intense heat and light emitted by an arc flash can cause severe burns, destroying skin and tissue. An arc flash can ignite or melt clothing, resulting in further burns. Victims sometimes require skin grafts or amputations. Death is more likely with increased severity of burns, the percent of body area affected and age. • A high-amperage arc can produce a pressure wave blast with a force of up to 1000 pounds. The victim can be thrown by the force of this pressure. Injuries can occur from falling or colliding with nearby objects. Hearing loss may also result from the blast. • The intense heat may melt metal electrical components and blast molten droplets considerable distances. These droplets harden rapidly and can lodge in a person’s skin, ignite clothing and may cause lung damage.

Ergonomics(Strain)

Damage of tissue due to overexertion (strains and sprains) or repetitive motion.

Ergonomics(Human Error)

A system design, procedure, or equipment that is error-provocative. (A switch goes up to turn something off).

Excavation(Collapse)

Soil collapse in a trench or excavation as a result of improper or inadequate shoring. Soil type is critical in determining the hazard likelihood.

Fall(Slip, Trip)

Conditions that result in falls (impacts) from height or traditional walking surfaces (such as slippery floors, poor housekeeping, uneven walking surfaces, exposed ledges, etc.)

Mechanical/Vibration(Chaffing/Fatigue)

Vibration that can cause damage to nerve endings, or material fatigue that results in a safety-critical failure. (Examples are abraded slings and ropes, Fatigue) weakened hoses and belts.)

Guidelines for Job Hazard Analysis – Draft 4/18/2008Mechanical Failure Self explanatory; typically occurs when devices exceed designed

capacity or are inadequately maintained.Mechanical Skin, muscle, or body part exposed to crushing, caught-between,

cutting, tearing, shearing items or equipment.Noise Noise levels (>85 dBA 8 hr TWA) that result in hearing damage

or inability to communicate safety-critical information.Radiation(Ionizing)

Alpha, Beta, Gamma, neutral particles, and X-rays that cause injury (tissue damage) by ionization of cellular components.

Radiation(non-Ionizing)

Ultraviolet, visible light, infrared, and microwaves (Non-Ionizing) that cause injury to tissue by thermal or photochemical means.

Struck By(Mass Acceleration)

Accelerated mass that strikes the body causing injury or death. (Examples are falling objects and projectiles.)

Struck Against Injury to a body part as a result of coming into contact of a surface in which action was initiated by the person. (An example is when a screwdriver slips.)

Temperature Extreme(Heat/Cold)

Temperatures that result in heat stress, Extreme exhaustion, or metabolic slow down such as hypothermia.

Visibility Lack of lighting or obstructed vision that results in an error or other hazard.

Weather Phenomena(Snow/Rain/Wind/Ice)

Self explanatory.
