Guidance on Safe Use
Administrative data
First-aid measures
INHALATION: If large amounts are inhaled, remove to fresh air. If breathing has
stopped, give artificial respiration. If breathing is difficult, administer
oxygen and call a physician.
EYE CONTACT: Immediately flush eyes with copious amounts of water for at least 15
minutes. Assure adequate flushing by separating eyelids with fingers.
Seek medical attention.
SKIN CONTACT: Immediately wash skin with soap and copious amounts of water while
removing contaminated clothing. Wash contaminated clothing before
reuse.
INGESTION: Induce vomiting by giving two glasses of water and sticking finger
down the throat. Consult a physician. Never give anything by mouth to
an unconscious person.
Fire-fighting measures
EXTINQUISHING MEDIA: Water spray, carbon dioxide, dry chemical powder or appropriate foam.
FIRE FIGHTING MEASURES: If excessive smoke or fumes are encountered, wear self-contained
breathing apparatus and protective clothing to prevent contact with
skin and eyes.
PROTECTIVE EQUIPMENT: A self contained breathing apparatus and suitable protective clothing
should be worn in fire conditions.
UNUSUAL HAZARD: Emits toxic fumes of carbon monoxide, carbon dioxide, and oxides of
sulfur and nitrogen under fire conditions. Sulfanilic acid can produce
flammable dust clouds in air. Take precautionary measures against
static discharges. If involved in a fire, it may emit noxious and toxic
fumes.
Accidental release measures
SPILLS OR LEAKS: Wear respirator, chemical safety goggles, chemical boots and
chemical gloves. Sweep up, place in drum and hold for approved
waste disposal in compliance with local, state, and federal
requirements. Avoid breathing dust. Avoid skin and eye contact and
inhalation.
PERSONAL PRECAUTIONS: Ensure suitable personal protection (including respiratory
protection) during removal of spillages.
ENVIRONMENTAL PRECAUTIONS: Do not allow to enter drains, sewers or watercourses.
METHODS FOR CLEANING UP: Protect against dust. Clear up spillages, transfer to a container for
disposal.Wash the spillage area clean.
Handling and storage
STORAGE: Store in well ventilated areas. Keep container tightly closed and dry.
Do not store with acids.
HANDLING:
SAFE HANDLING ADVICE: Control dust formation. Avoid contact with skin and eyes. Avoid
inhalation of high concentrations of dusts.
OTHER PREVENTION METHODS: Take precautionary measures against static discharges

ADDITIONAL ADVICE:
Sulfanilic acid is a mild organic acid and should be treated with care. This product should only be used as intended. Improper use of sulfanilic acid could cause damage to equipment or personnel. Proper protective equipment should always be worn when working with this material. This includes eye protection in the form of safety goggles and rubber gloves. If the product is handled in a fashion which causes dust to become airborne, then a dust mask or suitable respirator with particulate filters should be worn. If skin is contacted with sulfanilic acid, the exposed area should be washed with soap and water. If this material becomes in contact with the eyes, then an eye wash station should be used to irrigate the eyes for 10 minutes. After irrigation, the eyes may be treated with eye drops containing a buffering agent. The material safety data sheet (MSDS) should be reviewed prior to using this material.
Any spills of dry powder should be cleaned up using sweeping compound and placed proper containers. Liquid spills should be contained and pumped into appropriate containers. The exposed area should be neutralized using a weak base such as sodium bicarbonate. All waste must be properly disposed as directed by all governing laws.
Sulfanilic acid in dry form may be handling in mild steel equipment. However, once in solution, sulfanilic acid is moderately corrosive and should be processed using higher nickel alloys or in non-ferrous equipment.

Exposure controls / personal protection
RESPIRATORY PROTECTION: NIOSH/MSHA approved respirator.
PROTECTIVE GLOVES: Wear impervious chemical gloves as a standard handling procedure.
EYE PROTECTION: In cases where there is likelihood of eye contact, wear chemical
goggles.
VENTILATION: Normal criterion for workplace air changes.
Stability and reactivity
HAZARDOUS REACTIONS: Can react with acids (conditions to avoid).
HAZARDOUS DECOMPOSITION: Hazardous decomposition products. See "Fire fighting Measures".
Disposal considerations
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
