3 HAZARDS IDENTIFICATION
Emergency Overview
Colorless liquid, gas-like odor
DANGER!
EXTREMELY FLAMMABLE LIQUID AND VAPOR. VAPOR MAY CAUSE FLASH FIRE.
MAY CAUSE EYE IRRITATION.
MAY CAUSE RESPIRATORY TRACT IRRITATION.
MAY CAUSE ALLERGIC SKIN REACTION.
MAY CAUSE NAUSEA, HEADACHE OR DIZZINESS.
Potential Health Effects
Inhalation and skin contact are expected to be the primary routes of occupational exposure to this material. Based on
single exposure animal tests, it is considered to be slightly toxic if swallowed, no more than slightly toxic if absorbed
through skin, practically non-toxic if inhaled, practically non-irritating to skin and slightly irritating to eyes. Repeated or
prolonged contact may cause an allergic skin reaction. Vapor may be irritating to the eyes, skin and respiratory tract

and, with extreme overexposure, may cause a sense of coldness at the extremities, rapid heartbeat, cyanosis and
respiratory paralysis. This material has a strong objectionable odor that may cause nausea, headache, or dizziness.
4 FIRST AID MEASURES
IF IN EYES, immediately flush with plenty of water. Get medical attention if irritation persists.
IF ON SKIN, immediately wash with soap and plenty of water. Remove contaminated clothing and shoes.
Get medical attention if symptoms occur. Wash clothing before reuse. Thoroughly clean shoes before reuse.
IF SWALLOWED, do NOT induce vomiting. Give water to drink. Get medical attention immediately. NEVER
GIVE ANYTHING BY MOUTH TO AN UNCONSCIOUS PERSON.
IF INHALED, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give
oxygen. Get medical attention.

Extinguishing Media
Use water spray, carbon dioxide, foam or dry chemical.
Fire Fighting Instructions
Water may be ineffective. Use water spray or water fog to cool surrounding surfaces and prevent fire damage
or rupture of containers. Fire fighters and others who may be exposed to products of combustion should wear
full fire fighting gear (full Bunker Gear) and self-contained breathing apparatus (pressure demand NIOSH
approved or equivalent). Fire fighting equipment should be thoroughly decontaminated after use.
Fire and Explosion Hazards
When burned, the following hazardous products of combustion can occur:
Oxides of carbon
Sulfur oxides
Hydrogen sulfide
Vapors can travel to a source of ignition and flash back.
6 ACCIDENTAL RELEASE MEASURES
In Case of Spill or Leak
Extinguish or turn off ignition or combustion sources. Contain spill. Stop leak at source if this can be done
safely. Ventilate area only if odor control is not an issue. Nonessential personnel should leave the area until
cleanup is completed. Cover spill area with closed-cell foam to reduce odors (use of Aqueous Film Forming
Foam (AFFF) with polymeric layer is acceptable). If foam is unavailable, absorb spill with liquid-binding
material (e.g. diatomaceous earth, saw dust universal binder) and deodorize residue on ground with 3-10%
hydrogen peroxide. If spill is contained within a large containment area, add 5% bleach solution (sodium
hypochlorite) in a 50 parts bleach solution to one part product dilution ratio. Swimming pool chemicals
(hypochlorite compounds) work effectively in deodorizing product. If these are applied to product, the crystals

must be accompanied by sufficient water of dilution so that the considerable heat of reaction will be
absorbed. Enzyme or bacteria based deodorizers are also acceptable for use. Place waste materials into
Department of Transportation (DOT)-approved drums for disposal. Where practicable wash area down with
water. Keep concentrate and wash water from entering sewers or waterways. Consult a regulatory specialist
to determine appropriate state or local reporting requirements, for assistance in waste characterization and/or
hazardous waste disposal and other requirements listed in pertinent environmental permits.
7 HANDLING AND STORAGE
Handling
Keep away from heat, sparks and flame.
Keep container closed.
Use only with adequate ventilation.
Avoid contact with eyes.
Avoid prolonged or repeated contact with skin.
Wash thoroughly after handling.
CONTAINER HAZARDOUS WHEN EMPTY. Emptied container retains vapor and product residue. Follow
labeled warnings even after container is emptied. RESIDUAL VAPORS MAY EXPLODE ON IGNITION. DO
NOT CUT, DRILL GRIND OR WELD ON OR NEAR THIS CONTAINER. Improper disposal or reuse of this
container may be dangerous and/or illegal.
Storage
Store in well ventilated area away from heat and sources of ignition such as flame, sparks and static
electricity. Ensure that all storage and handling equipment is properly rated, grounded and installed to satisfy
electrical classification requirements. Static electricity may accumulate and create a fire hazard. All storage
containers, including containers such as drums, cylinders and IBC鈥檚, must be bonded and grounded during
filling and emptying operations. Store away from oxidizers and reactive materials. Keep container tightly
closed. Observe all federal, state and local regulations and National Fire Protection Association (NFPA)
Codes which pertain to the specific local conditions of storage and use, including OSHA 29 CFR 1910.106
and NFPA 30, 70, 77, and 497.
8 EXPOSURE CONTROLS / PERSONAL PROTECTION
Engineering Controls
Investigate engineering techniques to reduce exposures below airborne exposure limits. Provide ventilation
if necessary to control exposure levels below airborne exposure limits (see below). If practical, use local
mechanical exhaust ventilation at sources of air contamination such as open process equipment. Consult
ACGIH ventilation manual or NFPA Standard 91 for design of exhaust systems.
Eye / Face Protection
Where there is potential for eye contact, wear chemical goggles and have eye flushing equipment available.
Skin Protection
Wear appropriate chemical resistant protective clothing and chemical resistant gloves to prevent skin
contact. Consult glove manufacturer to determine appropriate type glove material for given application.
Wear face shield and chemical resistant clothing such as a rubber apron when splashing may occur. Rinse
contaminated skin promptly. Wash contaminated clothing and clean protective equipment before reuse.
Wash skin thoroughly after handling.

8 EXPOSURE CONTROLS / PERSONAL PROTECTION
Respiratory Protection
Avoid breathing vapor or mist. When airborne exposure limits are exceeded (see below), use NIOSH
approved respiratory protection equipment appropriate to the material and/or its components. Consult
respirator manufacturer to determine appropriate type equipment for given application. Observe respirator
use limitations specified by NIOSH or the manufacturer. For emergency and other conditions where
exposure limit may be significantly exceeded, use an approved full face positive-pressure, self-contained
breathing apparatus or positive-pressure airline with auxiliary self-contained air supply. Respiratory
protection programs must comply with 29 CFR 搂 1910.134.

11 TOXICOLOGICAL INFORMATION
Toxicological Information
Data on this material and/or its components are summarized below.
Spotleak 1450
Single exposure (acute) studies indicate that this material is slightly toxic if swallowed (rat LD50 3,160 mg/kg),
no more than slightly toxic if absorbed through skin (rat LD50 >2,000 mg/kg), practically non-toxic if inhaled (rat
1-hr LC50 >20 mg/l; vapor), practically non-irritating to rabbit skin and slightly irritating to rabbit eyes.
Isopropyl Mercaptan
Acute effects in rats during exposure to sublethal vapor concentrations of 18.44 mg/l or less for 4-hours were
attributed to the irritant nature of the vapors.
Dimethyl Sulfide
No skin allergy was observed in humans following repeated exposure. Administration in the drinking water of
rabbits produced increased lung weights and gross changes suggestive of effects in lungs and kidneys.
Repeated oral administration to rats and rabbits resulted in effects on the blood, lungs and kidney and some
organ weight changes. No genetic changes were observed in tests using bacteria, animal cells or animals.
tert-Butylmercaptan
In rodents, acute poisoning by this material produced a pattern of central nervous system depression, muscular
paralysis, and tremors. Skin allergy was observed in guinea pigs following repeated exposure. Following
repeated inhalation exposures, mild to moderate liver effect (hypertrophy) and mild kidney effects (proximal
tubular nephrosis in males only) were observed in rats. No birth defects were noted in the offspring of rats and
mice exposed by inhalation during pregnancy. No genetic changes were observed in tests using bacteria or
animals. Both positive and negative responses have been reported in tests using animal cells.
n-Propyl Mercaptan
Acute poisoning produced a pattern of central nervous system depression and respiratory paralysis in rodents
with death resulting from respiratory failure.
