Pneumatic tools, powered by compressed air, can be a useful and portable addition to electrical tools on construction sites. Follow this process in order to understand how to use them safely.
1. Ensure all workers who are authorized to use pneumatic tools are trained on safe tool operation
The air compressors that power pneumatic tools must be used correctly to ensure the safety of all workers on the job site. All workers who are authorized to use pneumatic tools should be trained on safe tool operation as well as inspection, compressed air hazards, proper PPE requirements and tool storage.
2. Understand the relevant OSHA standards
OSHA Standard 1926.302(b)(4): Compressed air shall not be used for cleaning purposes except where reduced to less than 30 PSI and then only with effective chip guarding and personal protective equipment.
3. Ensure you are wearing proper PPE and safety equipment
- Pneumatic tools can be noisy, so it is important to wear hearing protection when using air powered tools or when working in the area where they are used regularly.
- Eye protection is required, and head and face protection is recommended for crew members working with pneumatic tools.
- Gloves should be worn when using pneumatic tools to protect your hands.
- Dust masks should be used when using tools that create dust and fumes in the work area that may be hazardous.
- If pneumatic tools are used in areas where others are working, consider adding screens or shields to protect other employees from flying fragments, chips, dust and excessive noise.
4. Understand potential dangers of pneumatic tools and how to prevent injury
- Getting hit by an attachment or fastener that flies off can cause serious injury. Always use a safety clip or retainer to prevent attachments from being ejected during tool operation.
- A hose that becomes disconnected while still under high pressure can whip around wildly and strike workers in the area. Ensure all hose connections are secured by positive locking devices to prevent accidental disconnection during use.
- Electrical contacts within the air compressor motor or pressure switch can spark, creating a risk for fire or explosion. Operate air compressors in a well ventilated area away from combustible materials.
- Overheating can occur when ventilation openings on the air compressor are blocked Don’t place objects on or against the air compressor that could restrict airflow.
