What is OSHA approved air nozzle?

Compressed air used for cleaning purposes must be regulated to keep the pressure below 30 psi, or must use a nozzle with relief holes or other safety features (e.g., star tipped nozzle) that limit the air pressure to 30 psi or less when dead-ended (i.e., when the primary nozzle opening is held against a flat surface).

What makes an air gun OSHA compliant?

Output Pressure: Factory air lines normally operate between 80 psi and 120 psi. Most pneumatic tools, including air guns, need high pressures to operate effectively. OSHA requires that when an air gun is dead ended (the tip of an air gun is blocked), the static pressure at the point of blockage is no more than 30 psi.

What is OSHA regulated shop air pressure?

The enclosed Occupational Safety and Health Administration (OSHA) standard 29 CFR 1910.242(b) requires that compressed air used for cleaning purposes must be reduced to less than 30 psig (pounds per square inch gauge, 204 kPa).

What is a blowgun safety nozzle?

A blow gun is said to be “safe” when the air pressure measured at the nozzle, when the nozzle is blocked, or dead-ended, does not exceed 200 kPa. This pressure limit helps to reduce the risk of particles or air getting through the skin.

What is the maximum pressure that should be used with compressed air nozzles?

Today, most safety air gun nozzles have side ports that allow you to clean at higher pressures, such as 90 psi, but do not exceed 30 psi if the nozzle’s discharge end is blocked (also called “dead ended”). The side ports prevent the full velocity and force of the compressed air from causing an injury.

What are the requirements for pneumatic tools that operate at pressures in excess of 100 psi?

All pneumatically driven nailers, staplers, and other similar equipment provided with automatic fastener feed, which operate at more than 100 p.s.i. pressure at the tool shall have a safety device on the muzzle to prevent the tool from ejecting fasteners, unless the muzzle is in contact with the work surface.

What does OSHA consider high pressure?

High Pressure: Gas pressure greater than 20 MPa gauge (3000 psig) and liquid pressure greater than 35 MPa gauge (5000 psig).

What does OSHA consider high pressure air?

No employee shall be subjected to pressure exceeding 50 pounds per square inch except in emergency.

What is safety airgun?

Use engineered air nozzles for high performance! Inexpensive air guns are sold through many catalogs and industrial supply companies. Most have triggers or other parts that break quickly. The performance is similar to open pipe, where they simply blow a lot of compressed air.

What precautions should be taken when using compressed air?

Compressed Air Safety Caution

  1. NEVER POINT IT AT YOURSELF OR ANOTHER PERSON!
  2. NEVER USE IT TO CLEAN CLOTHING OR HAIR!
  3. ALWAYS FOLLOW PRESSURE RATINGS AND LIMITATIONS!
  4. ALWAYS CHECK THE CONDITION OF HOSES AND LINES BEFORE USE!
  5. ALWAYS WEAR PROPER PPE!
  6. ALWAYS WEAR PROPER PROTECTIVE CLOTHING.

At what pressure can air penetrate skin?

A pressure strong enough to dust or clean is strong enough to breach the skin and penetrate the body. Even pressures as low as 5-10 pounds per square inch (psi) can cause serious injury.
