1\. Assessment Scope

---

This Job Safety Analysis (JSA) covers the hydraulic hose replacement procedure on a Smartrock T45 drill machine. It includes all steps from preparation to completion, focusing on potential hazards and control measures. The scope excludes major repairs or overhauls of the hydraulic system beyond hose replacement.

2\. Risk Assessment Methodology

---

This risk assessment employs a systematic approach based on hazard identification, risk evaluation, and control implementation. The methodology follows these steps:

1\. Job Step Breakdown: Dividing the hose replacement task into sequential steps. 2\. Hazard Identification: Identifying potential hazards associated with each step through observation, experience, and consultation with workers. Questions are used to identify potential hazards, such as 'Can any body part get caught in or between objects?' and 'Do tools, machines, or equipment present any hazards?' 3\. Risk Assessment: Evaluating the initial risk for each hazard based on likelihood and severity. 4\. Control Measures: Determining and implementing control measures based on the hierarchy of controls (Elimination, Substitution, Engineering, Administrative, PPE). 5\. Residual Risk Assessment: Evaluating the residual risk after implementing control measures. 6\. Documentation: Documenting the entire process in a JSA.

The risk assessment uses a 5x5 risk matrix to determine risk ratings (Low, Medium, High, Extreme) based on likelihood and severity. [1] [1]

5\. General Control Measures

---

• Implement a comprehensive Lockout/Tagout (LOTO) program.

Ensure all energy sources are identified, isolated, and locked out before starting any maintenance or repair work. Train all employees on LOTO procedures and regularly audit the program for effectiveness.

• Conduct regular inspections of all tools and equipment.

Inspect tools and equipment before each use and remove any damaged or defective items from service. Maintain inspection records and ensure timely repairs or replacements.

• Provide and enforce the use of appropriate Personal Protective Equipment (PPE).

Ensure all employees wear appropriate PPE, including safety glasses, gloves, and footwear, when performing maintenance or repair work. Provide training on the proper use, maintenance, and storage of PPE.

• Maintain a clean and organized work area.

Keep work areas free from clutter, spills, and obstructions. Implement a regular cleaning schedule and ensure proper waste disposal.

• Ensure adequate ventilation in work areas.

Provide adequate ventilation to prevent the accumulation of hazardous fumes, vapors, or dust. Use local exhaust ventilation when necessary.

6\. Emergency Preparedness

---

• In case of hydraulic fluid injection injury, immediately seek medical attention. Do not delay, as this is a serious injury requiring specialized treatment.
• In case of a fire, activate the fire alarm, evacuate the area, and use a fire extinguisher if safe to do so. Contact emergency services.
• For hydraulic fluid spills, contain the spill using absorbent materials and dispose of properly according to environmental regulations. Report the spill to the appropriate authorities.

7\. Training Requirements
