LdV-3 Replaces date: 18/Nov/1999 ARGON EYE CONTACT Is not considered a potential risk. INGESTION Is not considered a potential risk. 5. FIRE FIGHTING MEASURES PROPER FIREFIGHTING EQUIPMENT Cool the cylinder with large amounts of water from a safe distance. IMPROPER FIREFIGHTING EQUIPMENT not applicable FIRE AND EXPLOSION HAZARDS Containers may explode if heated. The substance is not combustible. PERSONAL PROTECTION WHEN FIREFIGHTING If possible, fight fire from protected position. Use self-contained breathing apparatus if substance is involved in fire. OTHER INFORMATION Do not move any cylinder which has been involved in fire until it is cold. 6. ACCIDENTAL RELEASE MEASURES SAFETY MEASURES TO PROTECT PERSONS Evacuate personnel to safe area. Provide fresh air supply to closed/confined spaces.Vapours are heavier than air and may cause asphyxiation by reducing oxygen available for breathing. SAFETY MEASURES TO PROTECT THE ENVIRONMENT Not required PROPER METHODS FOR DAMAGE LIMITATION AND CLEANUP Stop leak if possible without risk. OTHER INFORMATION Vapours are heavier than air and may cause asphyxiation by reducing oxygen available for breathing. 7. HANDLING AND STORAGE HANDLING Suck back of water into the cylinder must be prevented. HANDLING ADVICE Use only equipment and materials approved for this gas. STORAGE Protect gas cylinders against direct sunlight, precipitation and corrosive environment.Secure gas cylinders to prevent them from falling; avoid shocks and heating. OTHER INFORMATION Do not expose cylinders to temperatures above 45 ºC.Gas cylinders must be equipped with valve protection caps during transport. 8.
