become permeated with liquid oxygen are impact sensitive and can detonate if

subjected to shock.

Keep Area and Exterior Surfaces Clean to Prevent Ignition

As normal industrial soot and dirt can constitute a combustion hazard, all equip-

ment surfaces must be kept very clean. Do not place oxygen equipment on as-

phalt surfaces, or allow grease or oil deposits to remain on benches or concrete

surfaces in the vicinity of the oxygen equipment. Use cleaning agents, which will

not leave organic deposits, on the cleaned surfaces. Equipment to be used in con-

tact with liquid oxygen should be handled only with clean gloves or hands washed

clean of oil.

Maintain Adequate Ventilation

Enclosed areas containing oxygen equipment should be ventilated to prevent ac-

cumulations of oxygen and thereby minimize combustion hazards.
