Question
Based on the identified hazard below in each of the categories of hazard. 1. Biological hazard - identified hazard: excrement in the restroom. 2. psychosocial hazard - identified hazard: work load pressure among students. 3. physical hazard - identified hazard: loose electrical switch board or wires. 4. chemical hazard - identified hazard: laboratory chemicals. Instructions: 1. assess each of the risk, and provide matrix table of each or how it can be categorized using matrix table. 2. implement right control measures like engineering, substitution, PPE, elimination and administration and give the reason why choosing that suitable control measures. 3. state the review or evaluation of the control

To effectively assess and manage the identified hazards, we will categorize each hazard using a risk matrix, propose suitable control measures, and provide an evaluation of those measures based on the context of the hazards identified.
### Step 1: Risk Matrix Assessment
The risk matrix typically uses the likelihood of an event occurring and the severity of its consequences to assess risk levels. Here, we categorize the identified hazards on a scale of Low, Moderate, High, and Very High.
#### Risk Matrix Table
| Hazard Category | Identified Hazard | Likelihood | Severity | Risk Level |
|----------------------|-------------------------------------------|---------------|---------------|---------------|
| Biological Hazard | Excrement in the restroom | Likely | Moderate | High |
| Psychosocial Hazard | Work load pressure among students | Possible | Moderate | Moderate |
| Physical Hazard | Loose electrical switch board or wires | Likely | Severe | Very High |
| Chemical Hazard | Laboratory chemicals | Possible | Severe | High |
### Step 2: Control Measures
For each identified hazard, we will select appropriate control measures based on the hierarchy of controls:
1. **Biological Hazard - Excrement in the restroom**
- **Control Measure:** Elimination and PPE
- **Reason:** Regular cleaning schedules should be implemented to eliminate the hazard. PPE, such as gloves and masks, can help protect maintenance staff who must clean the restroom.
2. **Psychosocial Hazard - Work load pressure among students**
- **Control Measure:** Administration and Training
- **Reason:** Implementing workload management programs, developing coping strategies workshops, and promoting open communication can alleviate pressure. This was chosen as it focuses on creating a supportive environment rather than direct elimination or substitution of stressors.
3. **Physical Hazard - Loose electrical switchboard or wires**
- **Control Measure:** Engineering Controls
- **Reason:** Repairing or putting covers on loose electrical wires potentially prevents incidents, which is an effective engineering control method to eliminate risks associated with electrical hazards.
4. **Chemical Hazard - Laboratory chemicals**
- **Control Measure:** Substitution and PPE
- **Reason:** Where possible, substitute hazardous chemicals with less harmful ones, and ensure that appropriate PPE (gloves, goggles, lab coats) is provided to prevent exposure to harmful substances.
### Step 3: Review or Evaluation of the Control Measures
1. **Biological Hazard**
- **Evaluation:** Cleanliness must be monitored regularly. Staff should be surveyed for any breaches in protocols. Effectiveness can be evaluated through reduced incidences of infections.
2. **Psychosocial Hazard**
- **Evaluation:** Surveys and feedback from students can provide insights into workload perceptions. Regular check-ins with student groups can measure the impact of programs implemented.
3. **Physical Hazard**
- **Evaluation:** Inspect wiring and switches regularly; conduct electrical safety audits. A significant reduction in electrical hazards and incidents will indicate control effectiveness.
4. **Chemical Hazard**
- **Evaluation:** Conduct regular safety audits of chemical storage and use. An effective measure will show a decrease in exposure incidences and improve understanding of chemical handling among students and staff.
### Conclusion
The above assessments and control measures form a comprehensive approach to hazard management across biological, psychosocial, physical, and chemical hazards in an educational or workplace environment. Regular reviews will be critical to adapt to new challenges and ensure ongoing safety and effectiveness.
