Safe handling of hazardous material Flashcards
(37 cards)
What is the definition of Toxic?
Acutely harmful to health
Toxic substances can cause significant health issues upon exposure.
What does Cytotoxic mean?
Acutely harmful to cells, disrupts DNA and drives apoptosis
Cytotoxic agents are often used in chemotherapy.
What is the meaning of Embryotoxic?
Acutely harmful to embryos/foetuses
Embryotoxic substances can lead to serious developmental issues.
Define Mutagenic.
Capable of changing genetic material
Mutagenic agents can lead to genetic mutations.
What does Carcinogenic refer to?
Capable of directly causing cancer
Carcinogenic substances increase the risk of cancer development.
What is Teratogenic?
Causes malformations in embryos/foetus
Teratogenic effects can lead to congenital disabilities.
What is the definition of Harm?
Adverse outcome or impact
Harm can result from exposure to hazardous substances.
Define Risk in the context of hazardous substances.
The matrixed combination of severity and likelihood
Understanding risk is essential for effective safety management.
What does Likelihood refer to?
The chance the harm event will occur under defined working conditions
Likelihood assessment helps in risk evaluation.
What is meant by Severity?
The seriousness of the harm
Severity helps in prioritizing safety measures.
What are Biological hazards?
Harmful organic substances e.g. proteins or blood
Biological hazards can lead to infections and diseases.
Define Chemical hazards.
Harmful inorganic substances e.g. bleach, 5-FU
Chemical hazards can cause toxicity and chemical burns.
What are Physical hazards?
Harmful environmental factors e.g. protease, noise, radiation, poor ergonomics and unsafe work areas
Physical hazards can lead to injuries and health issues.
What are Psychosocial hazards?
Not bio/chem/phys but have an adverse effect on well-being e.g. harassment, low control, workload and bad culture
Psychosocial hazards affect mental health and workplace morale.
What does HASWA 1974 stand for?
Health and Safety at Work Act
This act mandates reducing risks as far as is ‘reasonable practicable’.
What is the purpose of PPEWR 1992?
Mandates employers to provide PPE when exposed to risks
Personal protective equipment is crucial for worker safety.
What does COSHH 2002 regulate?
Control of substances hazardous to health
COSHH ensures safe handling of hazardous substances.
Name a criterion for defining hazardous drugs.
Carcinogenicity
Drugs meeting certain criteria are handled as hazardous.
What is the role of NIOSH?
US federal agency responsible for conducting research and making recommendations for the prevention of work-related injury and illness
NIOSH plays a crucial role in occupational safety.
What does WHO - IARC do?
Specialized cancer agency of the World Health Organization that categorizes chemicals into carcinogen groups
IARC has classified over 1000 agents.
List potential routes of exposure to hazardous substances.
- Ingestion
- Inhalation
- Dermal
- Mucosal membranes
- Percutaneous
Understanding exposure routes is vital for risk assessment.
What are some side effects of cytotoxic chemotherapy?
- Nausea and vomiting
- Hair loss
- Fatigue
- Decreased blood cell counts
- Infection risk
- Potentially fertility issues
Side effects can significantly impact patient quality of life.
