Question
To effectively assess and manage the identified hazards, each hazards will be categorized using a risk matrix, propose suitable control measures, and provide an evaluation of those measures based on the context of the hazards identified. The risk matrix typically uses the likelihood of an event occurring and the severity of its consequences to assess risk levels as outlined below.
1. Risk Assessment Matrix
Hazard Category Identified Hazard Likelihood (1-5) Severity (1-5) Risk Level (L/M/H)
Biological Hazard Excrement in the restroom 4 4 High
Psychosocial Hazard Workload pressure among students 3 4 Medium
Physical Hazard Loose electrical switchboard/wires 4 5 High
Chemical Hazard Laboratory chemicals 3 5 High
Likelihood and Severity Scale:
• 1 = Rare / Insignificant
• 2 = Unlikely / Minor
• 3 = Possible / Moderate
• 4 = Likely / Major
• 5 = Almost Certain / Catastrophic
2. Control Measures
A). Biological Hazard: Excrement in the Restroom
Control Measures: Elimination, PPE and Administration
Reason: Elimination is crucial as it focuses on reducing exposure through regular cleaning schedules and proper sanitation, which can significantly lower the risk of disease transmission; for example, daily cleaning of restrooms ensures that waste does not accumulate and fosters a healthier environment.
PPE, such as gloves and masks, serves as a vital barrier that protects workers from direct contact with harmful pathogens during the cleaning process; for instance, using nitrile gloves can prevent skin exposure to contaminants.
Lastly, administrative measures involve training staff on hygiene best practices, which cultivates awareness and proper behaviors; for example, training sessions can educate workers on the importance of washing hands thoroughly after cleaning to prevent cross-contamination. Together, these measures create a comprehensive approach to managing biological hazards effectively.
B). Psychosocial Hazard: Workload Pressure
Control Measures: Administration and Engineering
Reason: Administrative controls may include implementing flexible scheduling for teachers, such as staggered planning periods or shared responsibilities in grading, which can alleviate excessive workload during peak times like exam periods. For example, if a school allows teachers to collaboratively grade assignments over a shared online platform, it fosters teamwork and reduces individual pressure.
On the other hand, engineering controls could involve optimizing the use of technology in administrative tasks, such as utilizing software to streamline attendance tracking and grading processes.
For instance, adopting integrated school management systems can minimize administrative burdens and free up time for educators to focus on teaching and student interaction, ultimately reducing stress attributed to workload.
Together, these control measures create a more supportive work environment that mitigates the negative impacts of workload pressure.
C). Physical Hazard: Loose Electrical Switchboard/Wires
Control Measures: Engineering and Elimination
Reason: Engineering controls involve redesigning or modifying the existing electrical system to enhance safety; for example, installing secure, tamper-proof electrical enclosures can prevent students from accessing loose wires, thus reducing the risk of electric shock or fire.
Elimination, on the other hand, refers to completely removing the hazard from the environment; for instance, if a switchboard is identified as faulty and poses a significant risk, it should be replaced with a new, safer model that meets current safety standards.
By implementing these measures, schools can create a safer environment for students and staff by minimizing the dangers posed by loose electrical components.
D). Chemical Hazard: Laboratory Chemicals
Control Measures: Substitution, PPE and Engineering
Reason: Substitution involves replacing hazardous chemicals with safer alternatives; for example, using vinegar instead of hydrochloric acid for acid-base reactions reduces the risk of exposure to corrosive substances.
Personal Protective Equipment (PPE) is essential for safeguarding individuals against chemical spills or splashes; wearing goggles, gloves, and lab coats prevents direct skin and eye contact with hazardous materials.
Lastly, engineering controls focus on modifying the laboratory environment to minimize exposure to chemicals; for instance, installing fume hoods and proper ventilation systems ensures that harmful vapors are effectively exhausted, thereby protecting students and staff from inhalation risks.
Together, these measures create a safer laboratory environment conducive to learning while minimizing chemical risks.
