WHAT IS BIOLOGICAL
HAZARDS?
Biological hazards, also known as Biohazards, refer to Biological substances that pose a threat to the health of living organisms, primarily that of humans. This can include medical waste or samples of a microorganism, viruses, or toxins (from a Biological source) that can affect human health.
Answer:
1. EFFECT OF BIOLOGICAL HAZARDS
Biological health hazards include bacteria, viruses, parasites and moulds or fungi. They can pose a threat to human health when they are inhaled, eaten or come in contact with skin. They can cause illness such as food poisoning, tetanus, respiratory infections or parasite infection. We provide expertise and resources on monitoring and controlling biological hazards that are transmitted through food, air or water.
Some example of biological hazards are:
- Mold and fungi
- Blood and body fluids
- Sewage
- Airborne pathogens such as the common cold
- Stinging insects
- Harmful plants
Animal and bird droppings
WHAT IS CHEMICAL HAZARDS?
Chemical hazards. Chemical substances that have the ability to create a physical or health hazard are considered hazardous. Due to their properties chemical hazardous substances may be, but are not limited to being toxic, explosive, flammable, self-reactive, oxidizing, or corrosive.
Answer:
2. EFFECTS OF CHEMICAL HAZARDS
Chemicals can be toxic because they can harm us when they enter or contact the body. Exposure to a toxic substance such as gasoline can affect your health. Since drinking gasoline can cause burns, vomiting, diarrhea and, in very large amounts, drowsiness or death, it is toxic. Some chemicals are hazardous because of their physical properties: they can explode, burn or react easily with other chemicals. Since gasoline can burn and its vapors can explode, gasoline is also hazardous. A chemical can be toxic, or hazardous, or both
Toxity
Some substances are more toxic than others. The toxicity of a substance is described by the types of effects it causes and its potenc
- Potency
- Exposure:
- Routes of Exposure
- Dose
- Exposure medium
- Length of exposure
WHAT IS ERGONOMIC
HAZARDS?
Ergonomic hazards are physical conditions that may pose risk of injury to the musculoskeletal system, such as the muscles or ligaments of the lower back, tendons or nerves of the hands/wrists, or bones surrounding the knees, resulting in a musculoskeletal disorder.
Answer:
3. EFFECTS OF ERGONOMIC HAZARDS
Ergonomic hazards affect all workers (as well as their families) and industries and businesses of all sizes. Poor workplace design, repetitive move- ments, awkward body mechanics or postures, and other hazards produce or contribute to a stagger- ing number of disabling cumulative trauma ill- nesses and injuries.
Ergonomic hazards inculde:
- Improperly adjusted workstations and chairs
- Frequent lifting
- Poor posture
- Awkward movements, especially if they are repetitive
- Using too much force, especially if it’s done frequently
- Vibration
