An employer must report a work-related fatality to OSHA within 8 hours; an in-patient hospitalization, amputation, or loss of an eye must be reported within 24 hours.

OSHA 300A posting period

The annual summary of recordable injuries and illnesses, Form 300A, must be posted from February 1 through April 30 and retained with injury records for five years.

29 CFR 1910

The portion of OSHA regulations containing general industry standards; construction standards appear in 29 CFR 1926 and maritime standards in 29 CFR 1915 through 1918.

Fall protection trigger height

In general industry, fall protection is required when employees are exposed to falls of 4 feet or more to a lower level; construction standards use a 6-foot trigger.

Guardrail height

A standard guardrail has a top rail at 42 inches, plus or minus 3 inches, above the walking surface, with a midrail at approximately 21 inches.

Portable ladder setup

Non-self-supporting ladders are set so the base is one-quarter of the working length from the wall, a 4:1 ratio, and extended 3 feet above the landing.

Stair rail requirement

Stairways with four or more risers need a stair rail system on each unprotected side or edge, and handrails are mounted 30 to 38 inches above the tread nosing.

Minimum exit route width

Exit routes must be at least 28 inches wide at all points, with capacity of 0.2 inch per occupant on level surfaces and 0.3 inch per occupant on stairways.

Written EAP threshold

An employer with more than 10 employees must have a written emergency action plan; employers with 10 or fewer may communicate the plan orally.

Exit route ceiling height

The ceiling of an exit route must be at least 7 feet 6 inches high, and no projection may reduce the route width below the required minimum.

Fire prevention plan contents

A fire prevention plan lists major fire hazards, handling and storage procedures, potential ignition sources, fire protection equipment, and housekeeping responsibilities for controlling accumulations of flammable waste.

Guarding energized parts

Live parts operating at 50 volts or more must be guarded by enclosures, partitions, location in a qualified-person-only room, or elevation at least 8 feet above the floor.

Electrical working space

At least 3 feet of clear working space is required in front of equipment rated 600 volts or less, and the space must be 30 inches wide and 6.5 feet high.

GFCI protection

Ground-fault circuit interrupter protection is required for temporary receptacles and wet or damp locations, and on construction sites for all 120-volt, 15- and 20-ampere outlets.

Flexible cord restrictions

Flexible cords may not substitute for fixed wiring and may not run through walls, ceilings, floors, or doorways, nor be attached to building surfaces.

PPE hazard assessment

The employer must assess workplace hazards, select appropriate personal protective equipment, and certify the written assessment identifying the workplace evaluated and the person certifying.

Employer-paid PPE

OSHA requires employers to pay for required PPE, except non-specialty safety-toe footwear and non-specialty prescription safety eyewear that employees may wear off the job.

Hearing conservation threshold

A hearing conservation program, including audiometric testing and hearing protection availability, is required when noise exposure reaches an 8-hour time-weighted average of 85 decibels.

Respirator fit test

Employees using tight-fitting respirators must pass a fit test before initial use and at least annually, and must complete a medical evaluation before fit testing.

SDS section count

A safety data sheet contains 16 sections in a fixed order; Section 2 covers hazard identification and Section 4 covers first-aid measures.

GHS signal words

Hazard communication labels use only two signal words: Danger for the more severe hazards and Warning for the less severe hazards, matched to the hazard category.

HazCom written program

Employers must prepare and maintain a written hazard communication program describing how labels, safety data sheets, and employee training will be implemented at that workplace.

Secondary container labeling

Portable containers filled from a labeled container must also be labeled, unless the material is used immediately by the employee who dispensed it within the same shift.

Cylinder separation distances

Oxygen and fuel gas cylinders must be separated by at least 20 feet or by a noncombustible barrier at least 5 feet high having a half-hour fire rating.

Powered industrial truck evaluation

Operators must be trained and evaluated, then re-evaluated at least once every three years; refresher training is required after unsafe operation or an accident.

Storage stability rule

Materials stored in tiers must be stacked, blocked, or interlocked and limited in height so they remain stable and secure against sliding or collapse.

Clear aisles requirement

Aisles and passageways must be kept clear and in good repair, and permanent aisles must be marked so stored materials never block access or egress.

Machine guard requirements

Guards must prevent body parts from contacting moving parts, be secure, create no new hazard, and not interfere with normal machine operation or lubrication.

Abrasive wheel clearances

On a bench or pedestal grinder, the work rest must be adjusted to within 1/8 inch of the wheel and the tongue guard within 1/4 inch of the wheel.

Lockout tagout scope

Hazardous energy control applies to servicing and maintenance when a guard must be removed or bypassed, or when a body part enters a machine danger zone.

Power transmission guarding

Pulleys, belts, gears, shafts, sprockets, and chains that form a machine's power transmission system must be guarded to prevent employee contact with moving parts.
