,1. Presentation Content for Safe Materials Handling
This presentation is designed for all factory workers and should be engaging and practical.
Part 1: The Why - Safety First
Introduction: Acknowledge the critical role of every worker in ensuring safety.
Emphasize that safe materials handling is not just a rule, but a shared responsibility that
protects everyone.
Statistics and Impact: Share simple, relatable statistics on injuries from improper lifting
or handling. Show how these injuries affect not only work but also personal life.
Our Goal: To create a culture where every person goes home safe and healthy at the end
of every shift.
Part 2: The How - Methods and Best Practices
Manual Materials Handling (MMH):
o Proper Lifting Technique: Demonstrate the correct "lift with your legs, not your
back" method. Use a volunteer to show a proper and improper lift.
o Team Lifts: Explain when a lift requires two or more people. Emphasize clear
communication and synchronized movement.
o Use of Aids: Highlight the use of hand trucks, dollies, and other lifting aids to
reduce strain.
Mechanical Materials Handling (MMH):
o Forklift Safety: Stress the importance of certification and daily pre-use
inspections. Discuss the risks of speeding, improper load handling, and pedestrian
awareness.
o Crane and Hoist Safety: Explain the role of certified operators and the
importance of clear communication with a spotter.
o Clear Pathways: Discuss the need to keep walkways and work areas free of
clutter.
Part 3: Special Hazards at a Refinery
Hazardous Materials:
o Chemicals: Explain the risks of spills and leaks from corrosive or flammable
liquids. Review the location of Safety Data Sheets (SDS) and emergency spill
kits.
o Compressed Gases: Discuss the danger of unsecured cylinders and the need to
handle them with caution.
, Personal Protective Equipment (PPE):
o Required PPE: List and explain the purpose of PPE for materials handling,
including safety gloves, steel-toe boots, hard hats, and safety glasses.
o Correct Use: Demonstrate how to properly wear and care for PPE.
Part 4: Conclusion and Call to Action
Emergency Procedures: Briefly review what to do in case of a spill, leak, or injury.
Reinforce the "stop, assess, report" process.
Q&A Session: Open the floor for questions and feedback.
Commitment Pledge: End with a simple, memorable safety pledge that all workers can
commit to.
2. When to Conduct a Noise Exposure Risk Assessment
A Noise Exposure Risk Assessment should be conducted at a quarry under the following
circumstances:
Initial Assessment: When the quarry begins operations or when new equipment is
introduced that is likely to produce high noise levels.
Routine Review: Periodically, as mandated by health and safety regulations, to ensure
compliance and monitor changes.
Significant Changes: When there are major changes to the plant, equipment, or work
processes that could affect noise levels.
Reported Symptoms: If workers report symptoms of noise-induced hearing loss, such as
ringing in the ears (tinnitus) or difficulty hearing.
Seven Key Elements of the Assessment:
1. Identification of Noise Sources: Pinpoint all machines, processes, or activities that
generate noise, such as crushers, drills, and heavy-duty vehicles.
2. Measurement of Noise Levels: Use a sound level meter or personal dosimeters to
accurately measure noise levels (in decibels, dB) and the duration of exposure for
workers.
3. Identification of Exposed Employees: Determine which employees are exposed to
hazardous noise levels and for how long.
4. Assessment of Health Effects: Evaluate the potential for hearing loss and other health
issues based on the measured noise levels and duration of exposure.
5. Control Measures: Propose a hierarchy of controls to reduce noise exposure, prioritizing
elimination and engineering controls over administrative controls and PPE.
