WARNING
OXYGEN GAS CAN CAUSE A FIRE HAZARD
If you use oxygen as the plasma gas for cutting, it can cause a potential fire hazard
due to the oxygen-enriched atmosphere that collects. A fire can occur if oxygen is
not removed.
Hypertherm recommends that you install an exhaust ventilation system to remove
the oxygen-enriched atmosphere that can collect when oxygen is used as the
plasma gas for cutting.
Flashback arrestors are REQUIRED to stop the spread of fire to the supply gases
(unless a flashback arrestor is not available for a specific gas or pressure).
As an installer or user, you must supply the exhaust ventilation and flashback
arrestors for your cutting system. You can get them from your cutting machine
supplier.
WARNING

FATAL IF SWALLOWED

fatal if swallowed.
When you come into contact, flush skin or eyes with water. If swallowed, seek
immediate medical attention.
