People don't always realise that compressed air can cause severe injury or worse, even when there is no direct contact with the skin or body. This is a good option if a person has been sprayed with a chemical in the face and hair. To increase safety, and extra protection when blowing off, air guns with safety shields can be used to minimize the risk of chips and particle that can be blown behind safety glasses and cause potential injury. Hoses are best stored on a hose reel for longer life, and to avoid tripping hazards. Hear about how to protect people and equipment working with compressed air. Symptoms do not appear immediately after ultraviolet exposure but rather about four hours later. As a general rule, there are three risks.

It is forceful enough to blow an eye out of its socket or rupture an eardrum. According to OSHA the cause of eye injuries cost more than $300 million per year. This, in turn, can cause blood vessels to become blocked by air bubbles, triggering stroke-like symptoms.

Compressed air is used by most industries and is often used to blow off and clean work places of dirt and debris. Compressed air has a higher pressure than regular, atmospheric air, which means that there are a number of potential risks if it is handled incorrectly. In addition to standard chip guards, protective cone air nozzles can also be used to prevent chip fly-back. Maxillofacial air-containing cavities, blast implosion injuries, and management. As such, its essential for operators to employ effective chip guard barriers that block flying debris to prevent injuries. It is still recommended to exercise caution when using any machinery.
