SPECIAL FIRE FIGHTING PROCEDURE : EVACUATE AREA AND FIGHT FIRE FROM A SAFE DIS- TANCE OR A PROTECTED LOCATION. APPROACH FIRE FROM UPWIND. CONTAINERS MAY EXPLODE IN THE HEAT OF THE FIRE. USE WATER IN FLOODING QUAN- TITIES AS A SPRAY OR FOG TO KEEP FIRE-EXPOSED CONTAINERS COOL. APPLY WATER, AS ACID DILUENT, AS ABSORBENT OF NITROGEN OXIDE GASES, AND AS A COOLANT FROM AS FAR A DISTANCE AS POSSIBLE. MOVE CONTAINERS AWAY FROM FIRE AREA IF IT CAN BE DONE WITHOUT RISK. AVOID SPRAYING WATER DIRECTLY INTO THE ACID CONTAINER. USE WATER SPRAY OR FOG TO REDUCE OR DIRECT VAPORS. DO NOT ENTER WITHOUT WEARING SPECIALIZED PROTECTIVE EQUIPMENT SUITABLE FOR THE SITUATION. A FULL-BODY ENCAPSULATED CHEMIC- AL RESISTANT SUIT WITH POSITIVE PRESSURE SELF- CONTAINED BREATHING APPARATUS ( MSHA / NIOSH APPROVED OR EQUIVALENT ) MAY BE NECESSARY. TRAINED PERSONNEL MAY NEUTRALIZE SPILL. FIRE AND EXPLOSION HAZARDS: CONCENTRATED NITRIC ACID IS A STRONG OXIDIZER AND ITS HEAT OF REACTION WITH REDUCING AGENTS OR COMBUSTIBLE ORGANIC MATERIALS MAY CAUSE IGNITION OR EXPLOSION.

MUTAGENICITY: NA (NO HUMAN INFORMATION IS AVAILABLE). REPRODUCTIVE TOXICITY/SYNERGISTIC EFFECTS: NA PRIMARY ROUTES OF ENTRY: EYE CONTACT, SKIN CONTACT, INHALATION, AND INGESTION. ACUTE EFFECTS OF EXPOSURE: INHALATION: NITROGEN OXIDE GASES SUCH AS NITROGEN DIOXIDE PRESENT AT LOW LEVELS IN NITRIC ACID CONTRIBUTE SIGNIFICANTLY TO TOXIC EFFECTS OF INHALING VAPOR AND MISTS. SEVERITY OF EFFECTS ARE DEPENDENT ON THE CONCENTRA- TION OF ACID AND NITROGEN OXIDES, PARTICULARLY NITROGEN DIOXIDE, AND THE DURATION OF EXPOSURE. VAPOR OR MIST MAY CAUSE THE SENSATION OF A CHOKING, BURNING THROAT OR CAUSE COUGHING, CHEST PAIN AND DIFFICULT BREATHING. THESE SYMPTOMS MAY BE VERY MILD OR MAY BE DELAYED SEVERAL HOURS. OTHER MORE SERIOUS SYMPTOMS MAY DEVELOP WITHOUT PRIOR WARNING. WITIN 24 HOURS, SYMPTOMS OF MODERATE TO SEVERE BREATHING DIFFICULTIES AND BLUISH-COLORED SKIN (CYANOSIS) MAY PROGRESS VERY RAPIDLY TO CAUSE DEATH, BY SWELLING OF LUNG TISSUES (BRONCHOPNEUMONIA) OR FLUID IN THE LUNGS (PULMONARY EDEMA). (5,6) SKIN CONTACT: CAN CAUSE SEVERE BURNS AND PAIN. THE AFFECTED AREA (DEEPLY STAINED) MAY BECOME ULCERATED WITH THE DAMAGED SKIN SHEDDING OFF. PERMANENT SKIN DAMAGE OR SCARRING MAY RESULT.CONTACT WITH LARGE AREAS OF SKIN CAN BE FATAL IF THE ACID IS NOT WASHED AWAY IMMEDIATELY. (7) EYE CONTACT: VAPOR CAN CAUSE IRRITATION AND TEARING OF THE EYES. MISTS CAN PROBAB- LY CAUSE SEVERE IRRITATION OR INJURY IF EXPOSURE IS PROLONGED. CONTACT WITH CONCENTRATED NITRIC ACID LIQUID CAN CAUSE IMMEDIATE AND SEVERE TISSUE DAMAGE RESULTING IN BLINDNESS, WHICH MAY BE IRREVERSIBLE. (10) INGESTION: NITRIC ACID CAN CAUSE SEVERE PAIN AND CORROSIVE BURNS TO THE MOUTH, THROAT, ESOPHAGUS AND STOMACH IF INGESTED. SYMPTOMS MAY INCLUDE ABDOMIN- AL PAIN, NAUSEA, VOMITING, AND SHOCK. DEATH MAY OCCUR WITHIN HOURS OF SEVERE POISONING, OR MAY BE DELAYED FOR DAYS OR WEEKS. (7) SMALL AMOUNTS OF ACID (LESS THAN 10 mL) MAY BE FATAL. (4, 13) ACID WHICH ENTERS THE LUNGS DURING INGESTION OR VOMITING (ASPIRATION) CAN CAUSE SERIOUS LUNG INJURY AND DEATH. THE SYMPTOMS OF LUNG DAMAGE, SUCH AS BREATHING DIFFICULTIES MAY BE DELAYED FOR SEVERAL HOURS. SKIN ABSORPTION: NON IDENTIFIED CHRONIC EFFECTS OF EXPOSURE: DENTAL EROSION: REPEATED EXPOSURES TO NITRIC ACID VAPOR AND MIST MAY CAUSE THE BREAKDOWN OF TOOTH ENAMEL. MOST STUDIES DESCRIBE EXPOSURE TO BOTH SULFURIC AND NITRIC ACID. HOWEVER, ONE STUDY REPORTED THAT 3 OF 32 WORKERS EXPOSED TO NITRIC ACID ALONE HAD ACTIVE DENTAL ERRO- SION. (7) INHALATION EFFECTS: REPEATED EXPOSURE TO NITRIC ACID MISTS AND VAPOR MAY CAUSE LUNG DAMAGE SUCH AS SWELLING OF LUNG TISSUES AND AIR PASSAGES (CHRONIC PNEUMONITIS AND BRONCHITIS). (9) TARGET ORGANS: RESPIRATORY SYSTEM, LUNGS, EYES, SKIN, TEETH, MUCOUS MEMBRANE, AND GI TRACT. OTHER HEALTH HAZARDS: MEDICAL CONDITIONS GENERALLY AGGRAVATED BY EXPOSURE: RESPIRATORY DISEASE, CARDIO- PULMONARY DISEASE, EYE DISORDERS, LUNG DISEASE, AND DAMAGED SKIN. EMERGENCY AND FIRST AID PROCEDURES: INHALATION: TAKE PROPER PRECAUTIONS TO ENSURE YOUR OWN SAFETY BEFORE ATTEMPTING RESCUE; e.g., WEAR APPROPRIATE PROTECTIVE EQUIPMENT, USE THE " BUDDY " SYSTEM. REMOVE SOURCE OF CONTAMINATION OR MOVE VICTIM TO FRESH AIR. IF BREATHING IS DIFFICULT, OXYGEN MAY BE BENEFICIAL IF ADMINISTERED BY A PERSON TRAINED IN ITS USE, PREFERABLY ON A PHYSICIAN’S ADVICE. ENSURE VICTIM IS COMPLETELY AT REST, DO NOT ALLOW ANY PHYSICAL EXERTION. SYMPTOMS MAY BE DELAYED UP TO 48 HOURS AFTER EXPOSURE. IMMEDIATELY TRANSPORT VICTIM TO AN EMERGENCY MEDICAL CARE FACILITY. INGESTION: NEVER GIVE ANYTHING BY MOUTH IF VICTIM IS RAPIDLY LOSING CONSCIOUS- NESS, OR IS UNCONSCIOUS OR CONVULSING. HAVE VICTIM RINSE MOUTH THOR- OUGHLY WITH WATER. DO NOT INDUCE VOMITING. HAVE VICTIM DRINK 240- 300 mL (8 TO 10 OZ.) OF WATER. IF MILK IS AVAILABLE IT MAY BE ADMIN- ISTERED AFTER THE WATER HAS BEEN GIVEN. IF VOMITING OCCURS NATURALLY, HAVE VICTIM LEAN FORWARD TO REDUCE RISK OF ASPIRATION. REPEAT ADMIN- ISTRATION OF WATER. QUICKLY,TRANSPORT VICTIM TO AN EMERGENCY MEDICAL CARE FACILITY. EYE CONTACT: IN CASE OF EYE CONTACT, IMMEDIATELY FLUSH THE AFFECTED EYE(S) WITH PLENTY OF LUKEWARM, GENTLY FLOWING WATER FOR AT LEAST 20-30 MINUTES, BY THE CLOCK, HOLDING THE EYELID(S) OPEN. NEUTRAL SALINE SOLUTION MAY BE USED AS SOON AS IT IS AVAILABLE. DO NOT INTERRUPT FLUSHING. IF NECESSARY, KEEP EMERGENCY VEHICLE WAITING. TAKE CARE NOT TO RINSE CONTAMINATED WATER INTO THE NON-AFFECTED EYE OR ONTO THE FACE. IF IRRITATION PERSISTS, REPEAT FLUSHING. QUICKLY, TRANSPORT VICTIM TO AN EMERGENCY MEDICAL CARE FACILITY. SKIN CONTACT: IMMEDIATELY FLUSH SKIN WITH LUKEWARM WATER FOR AT LEAST 20-30 MIN- UTES, BY THE CLOCK. UNDER RUNNING WATER, REMOVE CONTAMINATED CLOTH- ING, SHOES, AND LEATHERWEARS (e.g., WATCHBANDS, BELTS). DO NOT INTERRUPT FLUSHING. IF NECESSARY, KEEP EMERGENCY VEHICLE WAITING. TRANSPORT VICTIM TO AN EMERGENCY CARE FACILITY IMMEDIATELY. COM- PLETELY DECONTAMINATE CLOTHING,SHOES, AND LEATHERWEARS BEFORE RE- USE OR DISCARD. ------------------------------------------------------------------------------- SECTION 6 - REACTIVITY DATA ------------------------------------------------------------------------------- STABILITY: NORMALLY STABLE. LIQUID EXPOSED TO LIGHT DECOMPOSES SLOWLY TO PRODUCE NITROGEN OXIDES, PRODUCING A YELLOWISH COLOUR. CONDITIONS TO AVOID: HEAT, LIGHT, AND WATER HAZARDOUS POLYMERIZATION: WILL NOT OCCUR. DECOMPOSITION PRODUCTS: HYDROGEN, AND OXIDES OF NITROGEN INCOMPATIBLES: NITRIC ACID IS AN OXIDIZING AGENT AND IS VERY REACTIVE. NITRIC ACID IS THE COMMON CHEMUCAL MOST FREQUENTLY INVOLVED IN REACTIVE INCIDENTS. (17) REFERENCES 8, 13 AND 17 REVIEW HAZARDOUS REACTIONS AND INCOMPATIBLE MATERIALS.
