<br /> ection fi, Health Hazard Datamr6nanued
<br /> Aeuto Elfectl:Inhalation of vapors or mists is corrosive to the respiratory tract and can cause tracheal and bronchial epithelium necrosis
<br /> (tissue death),cough,choking,ulceration Liquid aspiration can cause pulmonary edema,lung collapse,emphysema and damage to the
<br /> ulmonary blood vessels Skin contact with HCl solutions causes bums and ulcerations Permanent eye damage may result from splashes
<br /> tion is unlikely but if it occurs,symptoms include gray tongue color,corrosion of mucous membranm esophagus,and stomach,nausea,
<br /> lung.intense thirst.diarrhea.difficulty swallowing,circulatory collapse and possible death Chronic Effects-Repeated or prolonged
<br /> ire can cause dermatitis.conjunctivitis..gastritis,photasensttization.tooth erosion.and repeated exposure to mists from heated-metal
<br /> iekIung solutions can cause nose and gum bleeds,ulceration of oral or nasal mucosa,and"renders facial skin so tender that shaving is
<br /> aanfuL"033)
<br /> AID
<br /> Eyes-Do not allow victim to rub or keep eyes tightly shut.Gently hft eyelids and flush immediately and continuously with flooding amounts
<br /> f water until transported to an emergency medical facility Consult a physician immediately Skin Quickly remove contaminated clothing
<br /> with flooding amounts of water for at least 15 min Treat stun with a 5%tnethanolamine solution For reddened or blistered skin,
<br /> nisult a physician.Inhalation:Remove exposed person to fresh air and support breathing as needed Ingestion: Never give anytlung by
<br /> mouth to an unconscious or convulsing person Contact a poison control center Unless the poison control center advises otherwise,have that
<br /> Jisctous and alert person drink 1 to 2 glasses of water to dilute Do not induce vomitingl
<br /> r first aid,get appropriate in-plant,paramedic,or community medical support
<br /> ate to Physicians:Consider a chest x-ray in acute overexposure.
<br /> Secltion 7. Spill, Leak,and Disposal Procedures
<br /> pi11/I,ea3t:Notify safety personnel.isolate and ventilate area,deny entry,and stay upwind Neutralize spills with crushed limestone,soda ash,
<br /> or sodium bicarbonate.After neutralizing,take up small spills with earth,sand,vermiculite,or other absorbent,noncombustible material
<br /> and place in suitable containers for disposal,flush large spills to containment area and reclaim(if possible)or await disposal Follow applicable
<br /> OSHA regulations(29 CFR 1910 120) Environmental Transport:In soil.HCl will infiltrate moving faster rn the presence of moisture.It
<br /> ay dissolve some soul matter,particularly those of a carbonate base will be neutralized to some degree and will be transported to groundwater
<br /> toxicity Values:Chronic plant toxicity=100 ppm,injurious to trngatable crops at 350 mg/L,trout.LCiro, 10 mg/W4 hr shrimp,LCO,
<br /> O0 to 330 ppm/starfish,LCso, 100 to 330 mg/LAS hr,shore crab.LC,,,240 mg/L/48 hr Disposal- Neutralize to between 5 5&8.5 before
<br /> disposal Contact your supplier or a licensed contractor for detailed recommendations Follow applicable Federal,state,and Iocal regulations
<br /> PA Designations
<br /> as a RCRA Hazardous Waste(40 CFR 261.73,0 0IN solution or)igher) No D002.Characteristic of corrosivity
<br /> ted as a CERCLA Hazardous Substance*(40 CFR 302.4) Final Reportable Quantity(RQ).5000 lb(2270 kg)[*per CWA,Sec 311 (b)(4)]
<br /> SARA Extremely Hazardous Substance(40 CFR 355),TPQ Not lusted
<br /> as a SARA Toxic Chemical(40 CFR 372 65)

<br /> Listed
<br /> h
<br /> tor as an Air Contaminant(29 CFR 191010W,Table Z-1-A)
<br /> idh S. 5petial Protection Data
<br /> es:Wear chemical safety goggles,per OSHA eye-and face-protection regulations(29 CFR 1910 133) Because contact lens use in
<br /> s ]r is controversial,establish your own policy Respirator-Seek professional advice pnor to respirator selection and use.Follow OSHA
<br /> respiraregulations(29 CFR 1910 134)and,if necessary,wear a MSHA/NIOSH-approved respirator For<50 ppm,use a cartridge
<br /> orator with acid gas cartridges,or any supplied-air respirator(SAR)or SCBA For<100 ppm. use any chemical cartridge respirator with a
<br /> U facepiece and cartridge that protects against HCl inhalation,or any SAR or SCBA with a full faceptece. For emergency or nonroutine
<br /> Aerations(cleaning spills,reactor vessels,or storage tanks),wear an SCBA Warning►Air purifying respirators do not protect workers tri
<br /> oxygen-deficient atmospheres If respirators are used.OSHA requires a written respiratory protection program that includes at least.medical
<br /> cation,training,fit-testing,periodic environmental monitoring,maintenance,inspection,cleaning,and convenient,sanitary storage areas.
<br /> Wer:Wear chemically protective gloves,boats,aprons,and gauntlets to prevent skin contact.Polycarbonate,butyl rubber,polyvinyl
<br /> Londe,and chlorinated polyethylene are recommended materials for PPE.Polyvinyl alcohol is not recommended Ventilation: Provide
<br /> general and local exhaust ventilation systems to maintain airborne concentrations below the OSHA PEL(Sec 2) Local exhaust venulauon is
<br /> eared because it prevents contaminant dispersion into the work area by controlling it at its source(103)Safety Stations Make available in
<br /> e work area emergency eyewash stations,safety/quick-drench showers,and washing facilities Contaminated Equipment-Separate
<br /> ntaminated work clothes from street clothes Launder contaminated work clothing before wearing Remove this material from your shoes
<br /> and clean personal protective equipment. Comments:Never cat,drink,or smoke in work areas Practice good personal hygiene after using
<br /> this material,especially before eating.drinking,smoking,using the toilet,or applying cosmetics
<br /> eetidn %, Special Precautions and Comments
<br /> Storage Requirements:Prevent physical damage to containers Store in a cool,dry,well-ventilated area on a cement floor away from direct
<br /> might and heat sources Use decanting pumps or pouring frames to minimize spillage dunng loading and unloading operations
<br /> ugineering Controls To reduce potential health hazards,use sufficient dilution or local exhaust ventilation to control airborne contaminants
<br /> d to maintain concentrations at the lowest practical level HCl should be manufactured in closed systems Pay close attention to Ieak
<br /> detection Aqueous scrubbers are used to control hydrogen chloride emissions from vent stacks and other sources Workers shouldn't enter
<br /> tanks previously containing HCI until they have been cleaned.
<br /> lZinistrative Controls Consider preplacement and periodic medical exams of exposed workers with emphasis on the eyes,skin,and
<br /> ratory tract Pulmonary function tests(FEV.FVC)are useful in determining lung disorders Conduct difficult operations in fume hoods
