  EXPOSURE LIMIT FOR TOTAL PRODUCT, HEATED TO 300° F
  ACGIH TLV-TWA 5 mg/m3 NIOSH REL-STEL 5mg/m3 (15 minute time period)

For asphalt/sulfur fumes for an 8-hour workday recommended by the American Conference of Governmental Industrial Hygienist (ACGIH). OSHA Regulation 29 CFR 1910.1000 and the American Conference of Governmental Industrial Hygienist (ASCGIH) have adopted a Threshold Limit Value for the hydrogen sulfide (H2S) of 10 ppm (14 mg/m3) in air as a TEL OSHA Regulation 29 CFR 1910.1000 further lists a ceiling concentration of 20 ppm (28mg/m3), and a maximum peak of 50 ppm (70 mg/m3) for 10 minutes once per day if no other measurable exposure occurs. NIOSH-approved respiratory equipment should be used when permissible concentrations are extended.
  EXPOSURE LIMIT FOR HYDROGEN SULFIDE
ACGIH TLV-TWA 14 mg/m3
ACGIH TLV-STEL 21 mg/m3 		NIOSH-REL-CEIL 15mg/m3
(10 minute time period) 		OSHA PEL-STEL 50 ppm (Once per 8 hour shift)
OSHA PEL CEIL 0 ppm
  NIOSH-approved respiratory equipment should be used when permissible concentrations are extended. SEAM, due the subsequent major component being Sulphur, has not been shown to pose any significant health risks as with pure Sulphur.
C. PRIMARY ROUTES OF ENTRY AND EMERGENCY AND FIRST AID PROCEDURES
  EYE CONTACT:
If hot product is splashed into eyes, flush with clear water and contact physician.  May cause irritation to individuals that have a sensitivity to Sulphur and plastic dust type goggles are recommended.
  SKIN:
If skin is contaminated with cool, solid product, the contamination area should be cleaned with waterless skin cleanser followed by soap and water.
If skin is contacted with hot material, thermal burns will result. In this case, the contaminated area should be treated similarly to other thermal burns by cooling the affected immediately with the coldest available water. It is not usually advisable to immediately remove the material. Natural separation will occur in 48-72 hours. If removal is attempted, mineral oil (not mineral spirits) or mineral oil ointment may be applied to soften and facilitate removal. Remove all contaminated clothing.
  INHALATION:
Simple respirators, such as dust or nuisance odor masks, are recommended.
  INGESTION:
If ingested, DO NOT INDUCE VOMITING, call a physician immediately.

  C.O.C. FLASH WARNING:
Studies have shown that relatively low flash point substances, such as hydrogen sulfide and low-boiling hydrocarbons, may accumulate in the vapor space of mix storage silos. Such vapors may exhibit Flammability characteristics of a significantly lower flash product than would be indicated by the open cup flash test. As a precaution, keep ignition sources away from vents and openings, including prevention of accumulation of pyrophoric iron sulfide. Asphalt Institute Publication IS-180 and American Petroleum Institute Publication 852-20230 contain further information and guidance on the safe storage and handling of hot materials.
  EXTINGUISHING MEDIA AND FIRE FIGHTING PROCEDURES:
Foam, water spray (fog), dry chemical, carbon dioxide and vaporizing liquid type extinguishing agents may be suitable for extinguishing fires involving this type of product, depending on size or potential size of fire and circumstances related to the situation. Plan fire protection and response strategy through consultation with local fire protection authorities or appropriate specialists.

The following procedures for this type of product are based on the recommendations in the National Fire Protection Association's "Fire Protection Guide on Hazardous Materials", Eighth Edition (1984):

Use water spray, dry chemical, foam or carbon dioxide to extinguish the fire. Use water to keep fire-exposed containers cool. If a leak or spill has not ignited, use water spray to dispense the vapors and to provide protection for people attempting to stop a leak. Water spray may be used to flush spills away from exposures. Minimize breathing of gases, vapor, fumes or decomposition products. Use supplied-air breathing equipment for enclosed or confined spaces or as otherwise needed.

  DECOMPOSITION PRODUCTS UNDER FIRE CONDITIONS:
Fumes, smoke, carbon monoxide, hydrogen sulfide, sulfur oxides, aldahydes and other decomposition products, in the case of incomplete combustion.
E. HEALTH AND HAZARD INFORMATION
  VARIABILITY AMONG INDIVIDUALS
Health studies have shown that many petroleum hydrocarbons and synthetic lubricants pose potential human health risks, which may vary from person to person. As a precaution, exposure to liquids, vapors, mists or fumes should be minimized. SEAM, due the subsequent major component being Sulphur, has not been shown to pose any significant health risks as is the case with raw Sulphur.
  EFFECTS OF OVEREXPOSURE (Signs and symptoms of exposure)
High vapor concentrations (greater than approximately 700 ppm, attainable at elevated temperatures well above ambient) are irritating to the eyes and the respiratory tract, and may cause headaches, dizziness, anesthesia, drowsiness, unconsciousness, and other central nervous system effects, including death. See statements below regarding hydrogen sulfide (H2S).
  NATURE OF HAZARD AND TOXICITY INFORMATION
Skin contact with hot product may cause thermal burns. Prolonged or repeated contact with this product at warm or ambient temperatures tends to remove skin oils, possibly leading to irritation and dermatitis; however, based on human experience and available toxicological data, this product is judged to be neither a "corrosive" nor an "irritant" by OSHA criteria.

Eye contact with hot product may cause thermal burns. Contact with this product at warm or ambient temperatures may cause eye irritation but will not damage eye tissue. Simple respirators, such as dust or nuisance odor masks, are recommended.

CAUTION: Under certain circumstances, sulfur compounds in hot product may form hydrogen sulfide (H2S) gas. Cooling product may continue to emit traces of (H2S) temporarily from entrapped or dissolved gases. (H2S) is colorless, toxic and extremely flammable gas with an odor at low concentrations characteristic of rotten eggs and a sweetish odor at high concentrations. Odor cannot be relied upon as a means of detection because the sense of smell rapidly becomes insensitive to (H2S), and the (H2S) odor may be masked by the general odor of hot product. Because (H2S) may accumulate in tanks and bulk transport and storage compartments, personnel should stand upwind, keep their faces at least two feet from compartment openings, and avoid breathing vapors when opening hatches and dome covers.

Prolonged breathing of 50 to 100 ppm, of (H2S) may produce eye and respiratory tract irritation, headache, nervousness and nausea and only a few breaths of high concentrations (e.g. 700 to 1000 ppm) may lead to unconsciousness and could be fatal. NIOSH-approved respiratory equipment should be used when permissible concentrations are exceeded. The OSHA 8-hour Time Weighted Average Permissible Exposure Limit (TWA-PEL) is 10 ppm with a 15 minute Short Term Exposure Limit (TWA-STEL) of 15 ppm.
  DERMAL TOXICITY
The systemic toxicity of this substance has not been determined. However, it should be practically non-toxic to internal organs if it gets on the skin. This hazard is based on data from similar materials.

G. REACTIVITY
  This product is stable. Hazardous polymerization will not occur. Avoid contact with strong oxidants such as liquid chlorine, concentrated oxygen, sodium hypochlorite, calcium hypochlorite, etc. Hot product in contact with water can cause foaming or sudden evolution of steam, which could cause pressure build-up and possibly rupture a tank or vessel.

Hydrogen sulfide (H2S) from the product can react with the iron in an asphalt storage tank to form ferrous sulfide, which is pyrophoric.
H. ENVIRONMENTAL INFORMATION
  STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED

I. PROTECTION AND PRECAUTIONS
  PERSONAL HYGIENE
Minimize breathing vapor, mist or fumes. Avoid prolonged or repeated contact with skin. Remove contaminated clothing; launder or dry-clean before re-use. Remove contaminated shoes and thoroughly clean before re-use; discard if soiled. Cleanse skin thoroughly after contact, before breaks and meals, and at end of work period. Product is readily removed from skin by waterless hand cleaners followed by washing thoroughly with soap and water. SEAM has not been shown to pose any significant health risks as with pure Sulphur. ARP is similar to the health risks associated with asphalt cement or bitumen.
