APPENDIX A
SAFETY SUMMARY
The following are general safety precautions that are not related to any specific procedures and therefore, do not appear
elsewhere in this manual. These are recommendations that personnel should understand and apply during any phase of
operation or maintenance where applicable.
USE ALL POSSIBLE PRECAUTIONS WITH NITROGEN PRESSURE
All dry chemical and AFFF system piping and components should be considered charged until the system is deactivated
for any particular maintenance function.
Ensure that systems are deactivated before loosening any connection, hoses, or nozzles.
Never uncouple nozzles or connections to hose reel cart until hoses are depressurized and cleared.
Use care to ensure valves are closed, and protective covers installed, when possible, during installation, removal or
shipment of the high pressure nitrogen cylinders.
AVOID SPILLAGE OF CHEMICAL AGENTS
When possible during test procedures, drain hoses into suitable containers. AFFF concentrate is corrosive, and although
the dry chemical agents are considered non-toxic, discharge of large quantities may temporarily interfere with visibility.
Should the eyes become irritated from contact with either agent, flush immediately with clean fresh water. After spillage
of either fire-fighting agent occurs, the areas should be decontaminated immediately by flushing with water.
The following warnings appear in the text in this manual, and are repeated here for emphasis:
WARNING
Be sure lifting device is capable of lifting the specified weights, or personal injury could result.
