MIL-STD-1330D(SH)
20 September 1996
(e) Carefully check the system for leaks before pumping solvent through the system (see 5.8.3.2).
(f) Chemical safety goggles or a full-length face shield shall be worn where eye contact is possible. A full-length face shield shall be worn over chemical safety goggles for any operation where
splashing of the solvent may be a problem. In the event of eye contact, personnel should flush their eyes thoroughly with fresh water for not less than 15 minutes, then seek prompt medical attention. An eye wash system conforming to the design requirements of the American National Standards Institute (ANSI) Z358.1 shall be in the immediate vicinity of all operations. Eye wash systems shall provide not less than 15 minutes of water for emergency flushing.
(g) Repeated contact with the skin may cause cracking and irritation.
Wear solvent resistant rubber gloves if contact with the hands
cannot otherwise be prevented. Clothing that becomes saturated
with solvent should be removed at once.
(h) The atmosphere in the space where the solvent is used shall be
continuously monitored. An alarm shall be set on the instrument
which will be activated when the solvent reaches its recommended
exposure criteria. The concentration of the solvent shall not be
allowed to exceed the recommended exposure criteria during a
normal working day. If the alarm sounds, immediately put on the
EEBD and promptly leave the space. Anyone re-entering the space
should wear self-contained breathing apparatus operated in a
pressure-demand mode.
(i) An industrial hygienist, gas-free engineer, gas-free person, or
other designated individual shall verify that ventilation in the
space is adequate to keep the concentration of the solvent below
the recommended exposure criteria during anticipated operations,
excluding accidents or spills. If necessary use portable blowers.
Exhaust ventilation is preferable to blowing air into the space.
Solvent vapors should be captured as close as possible to the
point of generation and discharged outside of the area in a manner
that precludes recirculation and exposure to other personnel.
(j) In the event any adverse health effects are experienced, cease
operations involving halogenated solvents and consult the
cognizant medical department representative for additional
guidance. Should someone be overcome in a space which lacks
oxygen or because of the presence of a high solvent vapor
concentration, the person should be removed immediately and given
artificial respiration if necessary.
WARNING
SINCE HALOGENATED SOLVENTS MAY CAUSE CARDIAC SENSITIZATION, THE ATTENDING PHYSICIAN SHALL NOT ADMINISTER AN INJECTION OF EPINEPHRINE OR SIMILAR HEART STIMULANT AS CARDIAC ARRHYTHMIA,
INCLUDING VENTRICULAR FIBRILLATION, MAY RESULT. THE PATIENT SHOULD BE GIVEN FRESH AIR IMMEDIATELY AND SHOULD NOT BE ALLOWED TO EXERT HIMSELF OR HERSELF.
(k) When drying with nitrogen, solvent vapors and nitrogen shall be externally vented away from populated areas. If this cannot be accomplished, a gas-free engineer shall be consulted. It may be necessary to use an oxygen monitor to ensure there is not an excessive dilution of oxygen in the air.
(l) Emergency rescue procedures shall be established and proficiency documented to ensure that personnel can be safely removed in the event of hazardous exposures.
(m) Halogenated solvents used in contact with Diver Life Support Systems shall be completely drained and placed in an oven or heated to ensure all solvent is volatilized and removed before assembly, test, and operation. Air samples as specified in 5.9.3 are required to confirm removal of all solvent.
