ACCIDENT PREVENTION RECOMMENDATIONS

Employers are to require employees to wear suitable

personal protective equipment (safety belts) in all

operations where employees are exposed to hazardousconditions

Safety nets must be provided when workplaces are more

than 25 feet (7.62 m) above the ground or water surface, or

other surfaces where the use of ladders, scaffold, catchplatforms, temporary floors, safety lines, or safety belts is

not practical

Except where either permanent or temporary stairways or

suitable ramps or runaways are provided, suitable ladders

should be used to give safe access to all elevations

Hey Charlie, have

you seen my hardhat?

A carpenter apprentice was killed when he

was struck in the head by a nail that wasfired from a powder actuated tool.

The tool operator, while attempting to

anchor a plywood form in preparation for

pouring a concrete wall, fired the gun

causing the nail to pass through thehollow wall. The nail traveled some

twenty-seven feet (8.22 m) before striking

the victim.

The tool operator had never received

training in the proper use of the tool, and

none of the employees in the area werewearing personal protective equipment


Struck By example

Institute a program for frequent and regular

inspectionsof the job site, materials, andequipment by a competent person(s).

Regulations require employees exposed to the

potential hazards associated with flying nails to

use appropriate personal protective equipment.

Train employees using powder actuated tools in

the safe operation of the particular tool.

Train employees operating power actuated tools

to avoid firing into easily penetrated materials.

Had requirements for de-energizing energy sources

been followed, the electrocution might have been

prevented.

INSPECTION RESULTS


Ensure all circuits are de-energizedbefore beginning

work.Controls to be deactivated during the work on

energized or de-energized equipment or circuits must

be tagged.Employees must be instructed to recognize and
