Section 4: First Aid Measures
Eye Contact: Immediately flush with plenty of water for 15 minutes. Get medical attention. Prompt action may
save sight.
Skin Contact: Remove contaminated clothing and wash affected area with copious amounts of water. Call a
physician if irritation persists. Wash contaminated clothing prior to re-use.
Inhalation: Remove person to fresh air. Keep person calm. If not breathing, give artificial respiration. If
breathing is difficult give oxygen. Call a physician.
Ingestion: Do NOT induce vomiting. Immediately give milk, egg white, antacid, gelatin, or, if none of these are
available, give water. Get immediate medical attention.
Note to Physicians: Treat symptomatically.
Section 5: Fire-Fighting Measures
As defined by OSHA, this product is nonflammable.
Flammable Properties:
Flash Point: None Upper Explosive Limit: None
Autoignition Temperature: ND Lower Explosive Limit: None
Fire and Explosion Data:
Suitable Extinguishing Media: This material will not burn. Use water, CO2 or dry chemical as appropriate for
surrounding fire.
Products of Combustion: Heated material may produce corrosive and irritating fumes.
Explosion Hazards: Containers, when exposed to heat from fire, may build pressure and rupture.
Protection of Fire-Fighters: Firefighters should wear self-contained, NIOSH-approved breathing apparatus for
protection against suffocation and possible toxic decomposition products. Proper eye and
skin protection should be provided. Use water spray to keep fire-exposed containers cool
and to knock down vapors which may result from product decomposition.
Section 6: Accidental Release Measures
Personal Precautions: Use personal protection recommended in Section 8.
Environmental Precautions: Take precautions to prevent contamination of ground and surface waters. Do not flush
undiluted product into sewers or storm drains.

Product Number (s): MK3532, MK35128
Methods for Containment & Clean-up: Dike area to contain spill. Ventilate the area with fresh air. If in confined space
or limited air circulation area, clean-up workers should wear appropriate
respiratory protection. Neutralize spilled material with sodium bicarbonate
(baking soda) or sodium carbonate (baking powder, soda ash). Recover or
absorb spilled material using an absorbent designed for chemical spills. Place
used absorbents into proper waste containers.
Section 7: Handling and Storage
Handling Procedures: Keep containers closed while not in use. Do not mix with other chemical products. Use
appropriate personal protective equipment (see section 8) to prevent skin and eye contact.
Avoid breathing vapors. For product use instructions, please see the product label.
Storage Procedures: Store in a cool dry area out of direct sunlight. Containers should be tightly closed while in
storage. Do not store near alkaline materials. Keep out of reach of children.
Aerosol Storage Level: NA

Controls and Protection:
Engineering Controls: Area should have ventilation to provide fresh air. Local exhaust ventilation is generally
preferred because it can control the emissions of the contaminant at the source, preventing
dispersion into the general work area. Use mechanical means if necessary to maintain vapor
levels below the exposure guidelines. If working in a confined space, follow applicable OSHA
regulations.
Respiratory Protection: None required for normal work where adequate ventilation is provided. If engineering controls
are not feasible or if exposure exceeds the applicable exposure limits, use a NIOSH-approved
cartridge respirator with acid gas cartridge. Air monitoring is needed to determine actual
employee exposure levels. Use a self-contained breathing apparatus in confined spaces and
for emergencies.
Eye/face Protection: For normal conditions, wear safety glasses. Where there is reasonable probability of liquid
contact, wear splash-proof goggles.
Skin Protection: Use protective gloves such as latex or rubber. Also, use full protective clothing if there is
prolonged or repeated contact of liquid with skin.
