Study Notes

Personal Fall-Arrest Systems

A personal fall-arrest system must be secured to an anchorage point for safety.

Crane Operations

When a crane moves a load, it operates within a swing radius, posing risks to nearby workers from being caught between the crane or load and surrounding equipment or ground.

Ground Fault Circuit Interrupter (GFCI)

A GFCI protects from electrical shock by detecting current differences as small as 5 milliamps in a circuit.

Struck-by Accidents

Heavy vehicles contribute to struck-by accidents at worksites; their incidence can be mitigated with the use of back-up alarms.

Fall Protection Requirements

Fall protection measures are mandatory when workers are at risk of falling 6 feet or greater to a lower level.

Lockout/Tagout Procedures

Locking-out, tagging-out includes comprehensive safety practices to prevent accidental equipment operation.

Arc Flash Hazards

An arc flash presents multiple dangers, encompassing various risks to workers' safety.

Trench Safety

Trench depths of 5 feet or more require protective measures, which can include various safety protocols and equipment.

Passive Fall Protection

Passive fall protection systems incorporate various forms of protection that do not require active engagement by workers during a fall event.

Shock-Absorbing Lanyards

A shock-absorbing lanyard in a fall-arrest system is designed to slow and eventually stop a worker's descent while absorbing potentially injurious forces.

Jacking Equipment Specifications

Jacking equipment must support at least 2.5 times the load it is lifting for structural integrity.

Electrical Hazards

Cranes, ladders, scaffolds, and other machinery pose electrical hazards through potential contact with overhead power lines.

Electrical Power Tool Safety

Electrical power tools must be grounded, double insulated, powered by a low-voltage transformer, or use a self-contained battery for safety.

Traffic Control Measures

The advanced warning area in a MOT zone alerts motorists to upcoming construction activities, providing critical notice for safety.
