EntsorgungsverfahrenSRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational harm/injury/toxicity or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air qualitypotential migration in soil or watereffects on animal and plant lifeand conformance with environmental and public health regulations.
Preventive MeasuresSRP: The scientific literature for the use of contact lenses by industrial workers is inconsistent. The benefits or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.Personnel protection: Avoid breathing dusts, and fumes from burning material. Keep upwind. Avoid bodily contact with the material. Do not handle broken packages unless wearing appropriate personal protective equipment. Wash away any material which may have contacted the body with copious amounts of water or soap and water. If contact with the material anticipated, wear appropriate chemical protective clothing.If material is not on fire and not involved in fire: Do not use water. Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Keep material dry.All possible sources of ignition and friction should be eliminated. Good housekeeping, maintenance of gateways & exits, the provision of ... fire resisting personal protective equipment & training in fire drills are all necessary to minimize risks & to deal swiftly with any outbreak.Hand protection, barrier creams and strict cleanliness are necessary. A high standard of sanitary and washing facilities is necessary for all workersshower baths are particularly required for workers in storeroom & paste-making processes.

UmweltverhaltenTERRESTRIAL FATE: Phosphorus sesquisulfide decomposes (hydrolyzes) in water forming hydrogen sulfide and orthophosphoric acids(1). Therefore, hydrolysis is expected to be the dominant fate process in moist soil. Leaching and volatilization in moist soil are not expected to be important fate processes becuase of rapid hydrolysis(SRC). Biodegradation data were not available(SRC).AQUATIC FATE: Phosphorus sesquisulfide decomposes (hydrolyzes) in water forming hydrogen sulfide and orthophosphoric acids(1). Therefore, volatilization from surface waters, bioconcentration in aquatic organisms, and adsorption to sediment are not expected to be important fate processes with respect to phosphorus sesquisulfide(SRC).ATMOSPHERIC FATE: Appropriate estimation methods are not available to adequately predict vapor pressure or atmospheric reaction rates of phosphorus sesquisulfide.

Human Toxicity Excerpts/HUMAN EXPOSURE STUDIES/ Patch testing was performed with phosphorus sesquisulfide P4S3 in 2 groups containing equal numbers of patients using different concentrations (0.5% P4S3 in pet. and 1% P4S3 in pet., the usual suggested test concentration as recommended by the International Contact Dermatitis Research Group). /Investigators/ found that there was a statistically significant increase in the number of clinically irrelevant irritant reactions in the group tested with the concentration (X2= 16, P < 0.0004). /The authors/ recommend that patch testing with phosphorous sesquisulfide should be at a reduced concentration of 0.5% pet./HUMAN EXPOSURE STUDIES/ The results of patch testing with a series containing components of cigarettes and matches were reviewed. Two years were reviewed, 1987 and 1997. 314 patients were patch tested to this series, 203 in 1987 and 111 in 1997. 31 patients had clinically relevant positive reactions to the series, 25 in 1987 and 6 in 1997. 26 patients had relevant positive tests to cigarette components in the series. There were 14 relevant positive reactions to phosphorus sesquisulfide in 1987 and one in 1997. All patients with relevant positive reactions to red match tips also had reactions to phosphorus sesquisulfide. There was a significant association between cigarette and fragrance hypersensitivity. The eczema in 3 of 4 patients who stopped smoking improved. A series containing match heads, smoked cigarette filters and remnants of tobacco from smoked cigarettes may be useful in smokers with eczema of the face, neck or hands./SIGNS AND SYMPTOMS/ ...A rapidly developing erythema with formation of vesicles or pustules accompanied by pain and pruritis in handling phosphorus sesquisulfide /is reported among industrial workers/. Greasy skins were said to be most susceptible./CASE REPORTS/ Two months ago, a 32-year-old male waiter developed red, edematous, exudative and infiltrated plaques on the antero-lateral sides of both thighs, which were quite resistant to topical therapy. Scaly erythematous lesions on the eyelids and backs of the hands were also present. He used safety matches which he usually carried in his trouser pockets. The standard Spanish patch test series was negative. A test with the striking surface of his match box and with 0.5% phosphorus sesquisulphide produced an immediate, severe, urticarial response (at 20 min). Inspite of the fact that the tests had been removed immediately after the reading, there was an eczematous reaction at 48 hr, which lasted several days. The patient volunteered the information that he noticed and intense "taste of matches" in his mouth, several minutes after the patch test had been applied. When interviewed again, he mentioned that on lighting matches, he frequently observed an erythema and edema with itching on his hands and face. A biopsy showed a round cell infiltrate with slight acanthosis, exocytosis and spongiosis of the epidermis but no "lymphomatoid" appearance. On eliminating the use of matches the lesions cleared up with conventional local treatment, but persistent hypo-chromic plaques remained.For more Human Toxicity Excerpts (Complete) data for PHOSPHORUS SESQUISULFIDE (12 total), please visit the HSDB record page.
Artificial Pollution SourcesPhosphorus sesquisulfide's production and use in strike-anywhere matches and in organic synthesis(1) may result in its release to the environment through various waste streams(SRC).
Environmental BioconcentrationPhosphorus sesquisulfide decomposes (hydrolyzes) in water forming hydrogen sulfide and orthophosphoric acids(1). This suggests the potential for bioconcentration of phosphorus sesquisulfide in aquatic organisms is low(SRC).
Volatilization from Water/SoilPhosphorus sesquisulfide decomposes (hydrolyzes) in water forming hydrogen sulfide and orthophosphoric acids(1). This suggests that volatilization of phosphorus sesquisulfide from surface waters or moist soil will not be an important fate process(SRC).
Environmental Abiotic DegradationPhosphorus sesquisulfide decomposes (hydrolyzes) in water with the hydrolysis reaction slower in cold water but becoming faster upon heating, producing mainly hydrogen sulfide and orthophosphoric acid, H3PO4(1). In neutral solutions, the hydrolysis products include PH3 (3%), H3PO2 (38%), H3PO3 (49%) and H3PO4 (6)(1)in alkaline solutions, the hydrolysis products include PH3 (5%), H3PO2 (15%), H3PO3 (75%)(1).
Probable Routes of Human ExposureNIOSH (NOES Survey 1981-1983) has statistically estimated that 1,663 workers (298 of these were female) were potentially exposed to phosphorus sesquisulfide in the US(1). Occupational exposure to phosphorus sesquisulfide may occur through dermal contact with this compound at workplaces where phosphorus sesquisulfide is produced or used(SRC). Strike-anywhere matches may contain phosphorus sesquisulfide(2), therefore, the general population may be exposed to phosphorus sesquisulfide via dermal contact with these matches(SRC)./IN MATCH INDUSTRY/ THERE IS HIGH FIRE & EXPLOSION RISK IN MIXING OF PASTES & IN HANDLING OF HEADED MATCHES.
