Skin contact must be avoided at all times.
|
Seek medical attention
Immediately.
Triage procedures and medical management guidelines
- see ATSDR
medical management guidelines for Blister Agents.
|

|
Hold breath until respiratory
protective mask is donned.
Pressure demand, self-contained breathing apparatus
(SCBA) (SCBA CBRN, if available) is recommended in response
situations to any amount of agent
CBRN, Full Facepiece APR (when available) is recommended
in non-routine, emergency situation environments less
than IDLH but above REL or PEL levels. |

DECONTAMINATION |
Patients/Victims:
Remove clothes and place contaminated clothes and personal
belongings in a sealed double bag. Decontamination of
mustard-exposed victims by either vapor or liquid should
be performed within the first two minutes following
the exposure to prevent tissue damage. If not accomplished
within the first several minutes, decontamination should
still be performed to ensure any residual liquid mustard
is removed from the skin or clothes or to ensure any
trapped mustard vapor is removed with the clothing.
Removing trapped mustard vapor will prevent vapor off-gassing
or subsequent cross-contamination of other emergency
responders/health care providers or the healthcare facility.
Physical removal of the mustard agent, rather than detoxification
or neutralization, is the most important principle in
patient decontamination. Mustard is not detoxified by
water alone and will remain in decontamination effluent
(in dilute concentrations) if hydrolysis has not taken
place.
(1) Patients exposed to vapor should be decontaminated
by removing all clothing in a clean air environment
and shampooing or rinsing the hair to prevent vapor
off-gassing.
(2) Patients exposed to liquid should be decontaminated
by –
a. Washing in warm or hot water at least three times.
Use liquid soap (dispose of container after use
and replace), large volumes of water, and mild to
moderate friction with a single-use sponge or washcloth
in the first and second washes. Scrubbing of exposed
skin with a brush is discouraged, because skin damage
may occur which may enhance absorption. The third
wash should be to rinse with large amounts of warm
or hot water. Shampoo can be used to wash the hair.
The rapid physical removal of a chemical agent is
essential. If warm or hot water is not available,
but cold water is, use cold water. Do not delay
decontamination to obtain warm water.
b. Rinsing the eyes, mucous membranes, or open wounds
with sterile saline or water.
(3) The healthcare provider should –
a. Check the casualty after the three washes to
verify adequate decontamination before allowing
entry to the medical treatment facility. If the
washes were inadequate, repeat the entire process.
b. Be prepared to stabilize conventional injuries
during the decontamination process. Careful decontamination
can be a time consuming process. The health care
provider may have to enter the contaminated are
to treat the casualty during this process. Medical
personnel should wear the proper PPE and evaluate
the exposed workers.

medical management guidelines, SBCCOM
Guidelines for Mass Casualty Decontamination During
a Terrorist Chemical Agent Incident (January 2000),
and SBCCOM
Guidelines for Cold Weather Mass Decontamination During
a Terrorist Chemical Agent Incident (January 2002)
Equipment: Use 5% solution of common bleach
(sodium hypochlorite) or calcium hypochlorite solution
(48 ounces per 5 gallons of water) to decontaminate
scissors used in clothing removal, clothes and other
items.
Environment: (See Spillage Disposal.)
Common bleach (sodium hypochlorite or NaOCl), superchlorinated
bleaches
(calcium hypochlorite or Ca(OCl)2) and
chloramine can be used. |
SPILLAGE
DISPOSAL |
Cover with vermiculite,
diatomaceous earth, clay, or fine sand and neutralized
as soon as possible using large amounts of 5% sodium hypochlorite
solution. Scoop up all material and place in an approved
container. After sealing, decontaminate the exterior and
label. All leaking containers should be packed with sorbent
(e.g. vermiculite) and placed between the interior and
exterior containers. Label and dispose according to regulations.
Conduct general area monitoring.
If sodium hypochlorite solution is not available then
use the following in order of preference: Calcium Hypochlorite
and Super Tropical Bleach Slurry (STB). WARNING: Pure,
undiluted Calcium Hypochlorite (HTH) will burn on contact
with liquid blister agent. |

IMPORTANT DATA |
PHYSICAL
STATE; APPEARANCE:
Pure liquid is colorless and odorless. Forms yellow
prisms on cooling. Agent grade material is yellow to
dark brown or black and the odor is variously described
as similar to burning garlic, horseradish, a characteristic
sweetish odor, or a weak, sweet, agreeable odor.
PHYSICAL DANGERS:
Rapidly corrosive to brass at 65 °C. Will corrode
steel at a rate of 0.0001 in. of steel per month at
65 °C.
CHEMICAL DANGERS:
Stable at ambient temperatures. Decomposition temperature
is 300-351 °F (149-177 °C). Reacts with water
yielding hemi-mustard (a short-lived blister agent),
thiodyglycol, and hydrogen chloride (HCl) with a half-life
of 16 min. (see Environmental). On contact
with acid or acid fumes, it emits highly toxic fumes
of oxides of sulfur and chlorine. When heated to decomposition,
oxides of sulfur and chlorine are emitted.
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by all routes.
Tender skin, mucous membranes and perspiration-covered
skin are more sensitive to the effects.
INHALATION RISK:
MUSTARD, a chlorinated sulfur compound, is a blister
agent (vesicant) that causes severe, delayed damage
to the respiratory tract. It is an alkylating agent
that damages the cells within the bone marrow that are
necessary for making blood cells.
EFFECTS OF SHORT-TERM EXPOSURE:
MUSTARD damages the tissues the eyes, skin and respiratory
tract. The skin healing process is very slow. Exposure
to nearly lethal doses can injure the bone marrow, lymph
nodes, and spleen causing a drop in white blood cell
counts and an increased risk for developing infections.
MUSTARD exposure can also cause a cholinergic toxicity:
excessive saliva, tearing, urination, gastrointestinal
cramping and diarrhea, vomiting, small pupils.
EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The rate of detoxification is very slow in the body
and repeated exposures produce cumulative effects including
chronic lung impairment (cough, shortness of breath,
chest pain), cancer of the mouth, throat, respiratory
tract and skin, and leukemia. It may also cause birth
defects. A human carcinogen. |

ENVIRONMENTAL
DATA |
Bulk MUSTARD
can persist for decades in soil or water. When exposed
to sea water, mustard forms a thick outer "crust"
over a core of mustard which allows the mustard to be
brought to the surface where it can injure unsuspecting
fishermen who may snare plastic lumps of mustard gas in
their nets.
MUSTARD and a number of its hydrolysis products are oxidized
(air, oxygen, hypochlorite, hydrogen peroxide, nitric
acid, potassium permanganate, and chromic acid) to give
the less toxic sulfoxide and sulfone analogs.
MUSTARD and its hydrolysis products do not significantly
degrade in sunlight and are stable at less than 49°C.

NOTES |
HD is
distilled sulfur mustard which has been purified by washing
and vacuum distillation. H is Levinstein mustard which
contains about 30% sulfur impurities and has a stronger
vesicant action. HT consists of 60% HD and 40% T (a related
vesicant with lower freezing point and much lower volatility),
with reportedly similar characteristics to HD. T is not
expected to constitute an airborne vapor hazard.
