The purpose of this safety procedure is to provide the safety requirements for the use of power actuated fastening tools. This Instruction applies to all applications where power actuated tools are used on a project. Always refer to the power tool operating manual and cartridge operating manual.
Hazard Identification and Risk Assessment
The introduction of Power Actuated Fastening tools to the construction industry has enabled many trades to easily provide fixings into any substrate thus saving on costs of using older conventional methods.
However, in the wrong hands they can be very dangerous. It is essential therefore that these tools are used only by trained, certificated and experienced operatives who are over 18 years of age, and because cartridges are color coded, should not suffer from defective color vision.
Risk Checklist for Explosive Power Tools
The following types of risk may be present and will need to be assessed and the degree of risk reduced to that which is as low as reasonably practicable:
i. Untrained personnel.
ii. Eye, facial and body injuries.
iii. Misfire and associated safety procedures.
iv. Unauthorized use.
