Chemical Hazards Industrial Safety Lecture Three 5 6/4/2021
Categories of Hazardous Chemicals • • Corrosive (HCl , H 2 SO 4 , HNO 3 , NH 4 OH, KOH ) Flammable (Acetone, Nitromethane, Isopropyl alcohol) Toxic (Lead, Mercury, Hydrofluoric acid, Chlorine gas) Reactive (Phosphorus halides, Alkyl metals Na, Toluene diisocynate) • Biological (infectious eg. Bacteria, Viruses, Fungi, etc. ) • Carcinogen (Arsenic, Benzene, Cadmium, Vinyl Chloride, Radon, Hexavalent Chromium(VI) compounds ) • Radioactive ( Radon, Uranium Hexafluoride , etc. )
Chemical Hazards • • Pyrophoric (Spontaneously ignite in air) Flammable Chemicals Combustible Chemicals Oxidizers Industrial Safety Lecture Three 7 6/4/2021
Properties of Hazardous & toxic chemicals • Ignitability – liquids that have a flash point of less than 60◦C • Corrosivety –liquids have PH ≤ 2 or ≥ 12. 5 • Reactivity – substance that are unstable, react with violently with water. • Toxicity -
Chemical Exposure Severity & Duration • “Acute” effects usually occur rapidly as a result of short-term exposures, and are of short duration • “Chronic” effects generally occur as a result of long-term exposure, and are of long duration
Corrosive • Visible destruction, or irreversible damage to body tissue • Acids • Caustics (or bases) Acids p. H Scale 1 7 Caustics (or bases) 14
Routes of Exposure • Inhalation - most common • Skin absorption • Ingestion • Injection
Health Hazards Toxicity vs. hazard - toxicity is used to describe the ability of the substance to cause a harmful effect. Everything is toxic at some dose.
Health Hazards • • Sensitizers Target-Organ Chemicals Reproductive Hazards Carcinogens Industrial Safety Lecture Three 13 6/4/2021
Health Hazards • Irritants • Corrosives Industrial Safety Lecture Three 14 6/4/2021
Chemical Health Effects • • Irritants: Inflame skin tissue on contact. Corrosives: Destroy skin tissue at point of contact. Sensitizers: Cause allergic reactions. Target-Organ Chemicals: Damage specific body organs and systems. • Reproductive Hazards: Change genetic information in egg or sperm cells and/or damage fetus after conception. (Mutagens- substance that change genetic mutation ) (Teratogen - substance that cause malformation of an embryo or birth defect ) • Carcinogens: Cause cancer.

Material Safety Data Sheets (MSDS) are one of the most important tools available to employers for providing information, and protection to workers from hazardous chemicals which are used in the workplace.
1910. 1200 (g)(2) MSDS, required information • Identity of the chemical • Physical and chemical characteristics • Physical hazards • Chemical hazards • Primary routes of entry • PEL’s or other exposure limits • Control measures • Emergency procedures • Whether the hazardous chemical is listed in the National Toxicology Program (NTP) Annual Report on Carcinogens • precautions for safe handling and use • Date of preparation • Name, address and telephone of the manufacturer
Safe Chemical Handling
Working with Toxic chemicals 1. Keep containers closed when not in use 2. Keep away from ignition sources 3. Avoid contact with incompatible materials (Substances that should not be stored near each other because any contact between them cause a explosion. Eg. Sodium metal with water, in which hydrogen gas form which is explosive ) 4. Only transfer to approved containers 5. Bond all (A certificate of debt) receiving containers. 6. Clean up spills and dispose of waste properly
Working with Toxic chemicals 7. An explosion occurs when a material undergoes a rapid reaction that result in a violent release of energy. 8. Use the minimum amounts of hazardous materials with adequate shielding and personal protection. 9. Keep emergency equipment at hand.
ACCIDENT & INJURY PREVENTION • a. An unexpected and undesirable event, especially one resulting in damage or harm: car accidents on icy roads. • b. An unforeseen incident: A series of happy accidents led to his promotion. • c. An instance of involuntary urination or defecation in one's clothing. • 2. Lack of intention; chance: ran into an old friend by accident. • 3. Logic A circumstance or attribute that is not essential to the nature of something.
Types of Accidents • FALL TO – same level – lower level • CAUGHT – in – on – between • CONTACT WITH – – chemicals electricity heat/cold radiation • BODILY REACTION FROM – voluntary motion – involuntary motion
Types of Accidents (continued) • STRUCK – Against • stationary or moving object • protruding object • sharp or jagged edge – By • moving or flying object • falling object • RUBBED OR ABRADED BY – friction – pressure – vibration
Accident Causing Factors • Basic Causes – – Management Environmental Equipment Human Behavior • Indirect Causes – Unsafe Acts – Unsafe Conditions • Direct Causes – – Slips, Trips, Falls Caught In Run Over Chemical Exposure
Basic Causes Unsafe Acts Direct Causes Policy & Procedures Environmental Conditions Equipment/Plant Design Human Behavior Indirect Causes Slip/Trip Fall Energy Release Pinched Between ACCIDENT Personal Injury Property Damage Potential/Actual Unsafe Conditions
Accident Prevention Program • Must Be – Written – Tailored to particular hazards for a particular plant or operation • Minimum Elements – Safety Orientation Program – Safety and Health Committee
Accident Prevention Program • Safety Orientation – Description of Total Safety Program – Safe Practices for Initial Job Assignment – How and When to Report Injuries – Location of First Aid Facilities in Workplace – How to Report Unsafe Conditions & Practices – Use and Care of PPE – Emergency Actions – Identification of hazardous materials
Accident Prevention Program • Designated Safety and Health Committee – Management Representatives – Employee Elected Representatives • Max. 1 year • Must be equal # or more employee representatives than employer representatives – Elected Chairperson – Self-determine frequency of meetings • 1 hour or less unless majority votes – Minutes • Keep for 1 Year • Available for review by OSHA Personnel
Accident Prevention Program • Safety Meeting instead of Safety Committee – If less than 11 employees • Total • Per shift • Per location – Meet at least once/month – 1 Management Representative
Safety Meeting You Must – Review inspection reports – Evaluate accident investigations – Evaluate APP and discuss recommendations – Document attendance and topics
Safety Committees
Safety Committees Proactive Safety They should meet as often as necessary This will depend on volume of production and conditions such as • Number of employees • Size of workplace covered • Nature of work undertaken on site • Type of hazards and degree of risk Meetings should not be cancelled
Safety Committees The Goal of the committee is to facilitate a safe workplace Objectives that guide a committee towards the goal include: Motivate, educate and train at all levels to ID, Reduce, & Avoid Hazards Incorporate safety into every aspect of the organization Create a culture where each person is responsible for safety of self and others Encourage and utilize ideas from all sources
Four points to Remember: • Communication: Must be a loop system • Dedication: From everyone • Partnership: Between Management and Employees • Participation: An important part of team working.
How effective can a Committee be?
Safety Committee Policy Statement A written and publicized statement is an effective means of providing guidance and demonstrating commitment
