Hazards and Protection.
Storage
Store in a cool, dry location. Protect from freezing.
Handling
Keep away from childres, animals, food/feed, seed and fertilizer. Immediately clean up any spills which occure during handling.
Protection
Use waterproof gloves and face shield or goggles when handling concentrate.
Respirators
Wear MSHA/NIOSH approved respirator or mask.
Small spills/leaks
Absorb liquids by covering with an inert absorbent. Vacuum, scoop or sweep up and place in a container for disposal. Wash area with detergent solution and wrinse with water.
Stability
Stable at normal temperatures and pressures.
Incompatibilities
Strong oxidizing agents.
Decomposition
Hydrogen sulfide, oxides of carbon and sulfur.

Fire.
Fire fighting
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Use agent most appropriate to extinguish fire.

Exposure effects
Patients may acutely present with low heart rate, rapid heart rate, hyperventilation, respiratory depression even to the point of apnea, and/or hypo-/elevated blood pressure. Headache, vertigo, excitement or depression, loss of memory, and prostration may be observed. Tremors, seizures, coma, and death may result. Peripheral neuritis may follow after recovery. Spontaneous abortions have occurred after exposure to life-threatening concentrations.
   Ingestion
Exposure may result in a hydrogen sulfide odor on the breath or in gastric aspirate, difficulty in swallowing, and redness of the tongue and pharynx. Lime sulfur is irritating on contact to the mucous membranes. Vomiting, abdominal pain, and diarrhea may occur.
   Inhalation
Inhalation may result in shortness of breath, cough, tightness and burning of the chest, pulmonary edema, and even respiratory distress and failure. Pneumonia may occur after initial recovery.
   Skin
Lime sulfur is irritating to the skin; burns have been reported following ingestion. Molten sulfur burns cause severe dermal injury.
   Eyes
Injection of the the mucous membrane that lines the inner surface of the eyelid and the exposed surface of the eyeballe, seeing colored halos, ocular pain, corneal bullae, blurred vision and blepharospasm may be noted following exposure to 150 to 300 ppm.

First aid
 
   Ingestion
Emesis: ipecac-induced vomiting is not recommended because of the potential for cns depression and seizures. Consider after ingestion of a potentially life-threatening amount of poison if it can be performed soon after ingestion (generally within 1 hour). Activated charcoal: administer charcoal as a slurry (240 ml water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents. Patients should be monitored and treated symptomatically. Effects are variable depending on the route and amount of exposure. Hydrogen sulfide has been produced following ingestions of lime sulfur. Skin and eye irritation are possible following minor exposures. Moderate to severe effects can occur after large ingestions and result in gastrointestinal irritation and mucosal burns, as well as, cardiac, respiratory, and central nervous system effects.
   Inhalation
Move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with beta2 agonist and corticosteroid aerosols.
   Skin
Remove contaminated clothing and wash exposed area thoroughly with soap and water. A physician should examine the area if irritation or pain persists.
   Eyes
Irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility.
