2006-06 Hydrochloric Acid HYD2200 <br /> Potential Health Effects <br /> Target Organs: eyes,skin,respiratory system,liver(in animals) <br /> Primary Entry Routes: inhalation,skin contact,eye contact <br /> Acute Effects <br /> Inhalation: The vapor is extremely discomforting to the upper respiratory tract,may cause severe mucous membrane <br /> damage and may be harmful if inhaled. <br /> Inhalation of quantities of liquid mist may be extremely hazardous,even lethal due to spasm,extreme irritation of <br /> larynx and bronchi,chemical pneumonitis and pulmonary edema. <br /> A single severe exposure may cause coughing and choking;bleeding of nose,inflammation and occasionally <br /> ulceration of the nose,throat and larynx. Fluid on the lungs followed by generalized lung damage may follow. <br /> Breathing of vapor may aggravate asthma and inflammatory or fibrotic pulmonary disease. <br /> High concentrations cause necrosis of the tracheal and bronchial epithelium,pulmonary edema,atelectasis and <br /> emphysema and damage to the pulmonary blood vessels and liver. <br /> Inhalation hazard is increased at higher temperatures. <br /> The vapor from heated material is extremely discomforting to the upper respiratory tract and lungs if inhaled. <br /> Continued severe exposure can result in pulmonary edema and corrosion of tissues in the nose and throat. <br /> Eye: Hydrogen Chloride: The vapor is extremely discomforting to the eyes and is capable of causing pain and severe <br /> conjunctivitis. Corneal injury may develop,with possible permanent impairment of vision,if not promptly and <br /> adequately treated. <br /> The material may be irritating to the eye,with prolonged contact causing inflammation.Repeated or prolonged <br /> exposure to irritants may produce conjunctivitis. <br /> Hydrochloric Acid:Eye contact is extremely painful and may cause rapid corneal damage.The liquid is extremely <br /> corrosive to the eyes and is capable of causing severe damage with loss of sight. <br /> The vapor is highly discomforting and may be corrosive to the eyes.The vapor from heated material is extremely <br /> discomforting to the eyes. <br /> Skin: The material is corrosive to the skin and may cause chemical burns. <br /> Toxic effects may result from skin absorption.Bare unprotected skin should not be exposed to this material.The <br /> material may accentuate any pre-existing skin condition. <br /> The vapor is discomforting to the skin. <br /> Ingestion: Considered an unlikely route of entry in commercial/industrial environments. <br /> The liquid is extremely corrosive if swallowed and is capable of causing burns to mouth,throat,esophagus,with <br /> extreme discomfort,pain and may be fatal if swallowed in quantity.Ingestion may result in nausea,abdominal <br /> irritation,pain and vomiting. <br /> Carcinogenicity:NTP-Not listed;IARC-Group 3,Not classifiable as to carcinogenicity to humans;OSHA-Not <br /> listed;NIOSH-Not listed;ACGIH-Not listed;EPA-Not listed;MAK-Not listed. <br /> Chronic Effects: Chronic exposure may cause discoloration or erosion of the teeth,bleeding of the nose and gums;and <br /> ulceration of the nasal mucous membranes. <br /> Repeated exposures of animals to concentrations of about 34 ppm produced no immediate toxic effects. <br /> Workers exposed to hydrochloric acid suffered from gastritis and a number of cases of chronic bronchitis have also <br /> been reported. <br /> Repeated or prolonged exposure to dilute solutions may cause dermatitis.Repeated exposure to low vapor <br /> concentrations can cause skin tenderness,bleeding of the nose and gums,chronic bronchitis,gastritis. <br /> Section 4 - First Aid Measures <br /> Inhalation:Remove to fresh air. <br /> Lay patient down.Keep warm and rested. <br /> If breathing is shallow or has stopped,ensure clear airway and apply resuscitation.Transport to J�r <br /> hospital or doctor. 11 J <br /> Eye Contact: Immediately hold the eyes open and flush continuously for at least 15 minutes with <br /> fresh running water.Ensure irrigation under eyelids by occasionally lifting the upper and lower lids. <br /> Transport to hospital or doctor without delay.Removal of contact lenses after an eye injury should only be <br /> undertaken by skilled personnel. <br /> Skin Contact: Immediately flush body and clothes with large amounts of water,using safety shower if available. <br /> Quickly remove all contaminated clothing,including footwear. <br /> Wash affected areas with water(and soap if available)for at least 15 minutes.Transport to hospital or doctor. <br /> Ingestion: Contact a Poison Control Center.Rinse mouth out with plenty of water.Do NOT induce vomiting.Give a <br /> glass of water. <br /> After first aid,get appropriate in plant,paramedic,or community medical support. <br /> Note to Physicians:For acute or short-term repeated exposures to strong acids: <br /> 1.Airway problems may arise from laryngeal edema and inhalation exposure. <br /> Treat with 100%oxygen initially. <br /> 2.Respiratory distress may require cricothyroidotomy if endotracheal intubation is contraindicated by excessive <br /> swelling. <br /> Copyright©2006 Genium Group,Inc.Any commercial use or reproduction without the publisher's permission is prohibited.
