5.5 HAZARDOUS MATERIALS HANDLING TABLE 5.5-4 Toxic Effects and Exposure Levels of Regulated Substance Name Toxic Effects Exposure Levels-Pure NH3 Anhydrous Toxic effects for contact with pure liquid or vapor causes Occupational Exposures Ammonia eye, nose, and throat irritation, skin burns, and PEL=35 mg/m3 OSHA (99% NH3) vesiculation. Ingestion or inhalation causes burning pain TLV= 18 mg/m3 ACGIH in mouth, throat, stomach, and thorax, constriction of TWA= 18 mg/m3 NIOSH thorax, and coughing followed by vomiting blood, STEL=35 mg/m3 breathing difficulties, convulsions, and shock. Other Hazardous Concentrations symptoms include dyspnea, bronchospasms, pulmonary IDLH = 300 ppm edema, and pink frothy sputum. Contact or inhalation LD50=350 mg/kg-oral, rat overexposure can cause burns of the skin and mucous ingestion of 3 to 4 mL may be fatal membranes, and headache, salivation, nausea, and Sensitive Receptors vomiting. Other symptoms include labored breathing, ERPG-1 =25 ppm bloody mucous discharge, bronchitis, laryngitis, ERPG-2 =200 ppm hemmoptysis, and pneumonitis. Damage to eyes may be ERPG-3 = 1,000 ppm permanent, including ulceration of conjunctiva and cornea and corneal and lenticular opacities. ERPG = Emergency Response Planning Guideline ERPG-1 = Maximum airborne concentration below which nearly all individuals could be exposed for up to 1 hour without experiencing other than mild transient adverse health effects ERPG-2= Maximum airborne concentration below which nearly all individuals could be exposed for up to 1 hour without developing irreversible or serious health effects ERPG-3= Maximum airborne concentration below which nearly all individuals could be exposed for up to 1 hour without experiencing life-threatening health effects IDLH = Immediately dangerous to life and health LD50= Dose lethal to 50 percent of those tested mg/kg = milligrams per kilogram Mg/M3= milligrams per cubic meter mL= milliliters PEL=OSHA-permissible exposure limit for 8-hour workday ppm =parts per million STEL= Short-term exposure limit, 15-minute exposure TLV=ACGIH threshold limit value for 8-hour workday TWA= NIOSH time-weighted average for 8-hour workday Ammonia will only be transported along approved transportation routes. The recommended routes, subject to Caltrans approval, are as follows: • From I-5 exit at SR 12 interchange then turn south onto North Thornton Road,west on Frontage road, and south on North Cord Road; • From I-5 exit at West Eight Mile Road interchange then turn north onto North Thornton Road, west on Frontage road, and south on North Cord Road; Outbound trucks would proceed on 1-5 to access hazardous waste facilities throughout the state. Hauling would be carried out in accordance with local, state, and federal regulations that include the Resource Conservation and Recovery Act (42 U.S. Code 6901 et seq.) and the California Integrated Waste Management Act (Public Resources Code Sections 40000 et seq.). 5.5-16 SAC/371322/082330015(LEC_5.5_HAZMAT.DOC)
