Pneumatic Tool Operator: 7 Simple Steps To Ensure Safety

Not all pneumatic tools need to be intrinsically safe. Intrinsic safety is a specific requirement in workplaces where there is a risk of explosion due to the presence of gases, vapours, mists, or dust. Examples include chemical refineries, offshore platforms, flour mills, and paint shops. In hazardous environments like these, pneumatic power tools can act as a source of ignition. To prioritize operator safety in these situations, it is essential to choose pneumatic tools that have been specifically designed and certified for intrinsic safety. Essentially, this means the tool has been designed to limit the energy - electrical and thermal - available for ignition.

Employers are legally obliged to perform a risk assessment to ensure safe working environments, which classifies areas into zones. These classifications can be used to identify the right type of tools that will perform safely in each zone. In Europe, the ATEX Directive defines these zones and outlines the requirements and certification procedures for equipment to be used in potentially explosive atmospheres. Similar regulations exist in other geographies, such as DSEAR in the UK and NEC and IEC in North America.

With this in mind, here are seven simple steps to reduce the risk of accidents and ensure a pneumatic tool operator safety.

Best Strategies for Pneumatic Tools Safety

Pneumatic tools, also known as air tools, include chippers, drills, hammers, jackhammers, nail guns, and wrenches that are powered by an air compressor. They share safety issues with electric and gas-powered tools, but the high pressure of compressed air introduces additional risks. This article highlights the best strategies for pneumatic tool safety; if you cannot understand and implement these steps, it may be better to avoid using air tools.

One essential safety tip from OSHA is to avoid being struck by attachments that can become detached. Always use a safety clip or retainer to keep attachments, such as chisels on a chipping hammer, firmly secured during operation.

Pneumatic tools that shoot nails, rivets, or staples and operate at pressures exceeding 100 psi must be equipped with a device that prevents fasteners from being ejected unless the muzzle is pressed against the work surface. Installing safety retainers is crucial to prevent incidents during tool operation.

Air Hose Safety When Using Pneumatic Tools

Air hoses feed air to tools, making it vital to inspect them before use. Check that tools are securely fastened to the air hose; a short wire or positive locking device should also be used for added safety. If an air hose has a diameter larger than ½ inch, install a safety excess flow valve at the air supply to mitigate pressure in case of hose failure. Unused or improperly secured hoses can whip around, posing a hazard to workers nearby.

Eye Protection is Essential

Wearing eye and head protection is crucial when operating pneumatic tools. It's wise to alert others nearby to maintain a safe distance. PPE, including safety glasses or goggles and noise-canceling gear, is necessary due to the louder nature of pneumatic tools. Protective measures can shield you from flying debris like nails and wood chips, and screens can safeguard coworkers.

Make safety a priority by exploring and adhering to all relevant guidelines.

OSHA Regulations for Pneumatic Tool Safety

Refer to OSHA's Construction Standard for Pneumatic Power Tools, specifically 29 CFR .302 (b).

Tend Industrial Supplies Top 5 Pneumatic Tool Safety Tips

When using pneumatic tools like nail guns, drills, and hammers, the technical team at Tend Industrial Supplies recommends the following safety precautions, aligning with OSHA's standards:

1. Always read the product manual.

Consult the manufacturer’s operating instructions for specific handling, usage, warnings, and maintenance procedures.

2. Wear proper personal protective equipment (PPE).

Ensure high-impact body protection, such as safety glasses, and provide safety toe shoes, hard hats, and hearing protection at no cost to employees.

3. Follow product guidelines for air pressure and use relief couplers.

Maintain air pressure within safe ranges and avoid using compressed air for cleaning tasks on oneself or clothing. Always opt for relief-type couplers when connecting tools to air supplies.

4. Never carry tools by the hose.

Disconnect tools from air supplies when not in use to prevent accidental discharges. If operating at heights, secure air tools with lanyards.

5. Know your trigger and its operation.

Familiarize yourself with the various trigger mechanisms to enhance safety; do not modify your tools, as this can bypass safety systems.

In summary, the safe operation of pneumatic tools is vital to preventing workplace injuries. Implementing the top strategies, such as following manufacturer guidelines, regular equipment inspections, and ensuring adequate PPE, greatly reduces risks.
