Types Of Hazards • CHEMICAL AND PHYSICAL HAZARDS – EH&S • RADIATION AND BIOLOGICAL SAFETY –Prospective Health • EMPLOYEE HEALTH –Prospective Health • ANIMAL HANDLING –Comparative Medicine
Types Of Chemical Hazards Health Hazards Physical Hazards Explosive Flammable Gases Under Pressure Pyrophoric Self-Reactive Water Reactive Oxidizer Organic Peroxide Corrosive to Metals • Acute Toxicity • Carcinogenicity • Reproductive Toxicity • Skin Corrosion/Irritation • Respiratory or Skin Sensitization • Aspiration Toxicity • Target Organ Systemic Toxicity • Hazardous to Aquatic Environment
Effects Of Exposure • ACUTE - direct threat that shows up almost immediately after exposure such as burns from contact with a corrosive chemical • CHRONIC - usually result from repeated exposure that occurs over months or years and includes cancer and some allergic reactions
Routes Of Exposure • INHALATION • ABSORPTION • INGESTION • INJECTION The most likely target depends upon the characteristics of the material being used.
ROUTES OF EXPOSUREINHALATION • Primary Route of Entry • Airborne contaminants such as gases, vapors and particulate matter that enter directly into lungs. • Chemical fume hood is the primary control available. • Respiratory protection or specialized exhaust may be necessary where a fume hood cannot be used.
ROUTES OF EXPOSUREABSORPTION • Can occur very quickly through cuts or abrasions on the skin. • Depending on the characteristics of the contaminant, absorption may occur through intact skin (example: phenol) • Mucous membranes and eye tissue are particularly vulnerable • Barrier protection (such as gloves) and personal hygiene are the primary control measures.
ROUTES OF EXPOSUREINGESTION • Includes direct tasting of chemicals. • More often occurs when contaminated items are placed in the mouth. • Purpose for banning food, drink, tobacco, and cosmetics in the lab. • Personal hygiene, labeling and housekeeping are very important to ingestion hazard control.
ROUTES OF EXPOSUREINJECTION • Includes all puncture wounds. • Examples: needle sticks, glass shards or capillary tubes puncturing skin • Difficult to protect against • Use carefully planned procedures and personal diligence, including needle blocks.
