- Prioritize risks: Based on the evaluation, risks should be prioritized according to their potential impact on worker safety and business operations. This prioritization will help guide the development of appropriate safety measures and controls.
- Implement safety measures: Once the risks have been prioritized, appropriate safety measures should be implemented to mitigate the identified hazards. These measures may include engineering controls, administrative controls, and personal protective equipment (PPE).
- Monitor and review: The final step in the risk assessment process is to monitor and review the effectiveness of the implemented safety measures. This ongoing process ensures that the safety measures remain effective and allows for adjustments as needed.
Engineering Controls: Designing Safety into Machines
Engineering controls are physical modifications or designs that eliminate or reduce potential hazards. These controls can be built into the machine during the design phase or added later as retrofits. Some examples of engineering controls include:
Machine Guarding
Machine guarding uses barriers or shields to protect workers from moving parts, sparks, and other hazards. Standard machine guards include fixed guards, adjustable guards, and self-adjusting guards. These guards should be designed to prevent unauthorized access to hazardous areas while allowing for proper machine operation and maintenance.
Safety Interlocks
Safety interlocks prevent the machine from operating unless certain safety conditions are met. For example, an interlock may prevent a machine from starting unless all the guards are in place, or it may stop the machine if a worker enters a hazardous area. Interlocks can be mechanical, electrical, or electronic and should be designed to prevent bypassing or tampering.
Emergency Stop Devices
Emergency stop devices are controls that allow workers to quickly and easily stop a machine in an emergency. These devices should be clearly labeled, easily accessible, and designed to prevent the machine as soon as possible without creating additional hazards.

Proper training ensures workers understand the risks associated with their jobs and know how to operate machines safely. Training programs should cover topics such as hazard identification, safe operating procedures, and the use of PPE. Refresher training should be conducted periodically to ensure that workers remain aware of safety procedures and any changes that may have been made.
Lockout/Tagout Procedures
During maintenance and repair, lockout/tagout procedures ensure that machines are properly shut down and isolated from energy sources. These procedures help prevent the accidental startup of machines, which can lead to severe accidents and injuries.
Personal Protective Equipment: Providing the Last Line of Defense
Workers wear PPE to protect against hazards and minimize the risk of injury. PPE should be considered the last line of defense, as it does not eliminate hazards but provides protection when other safety measures fail or are not feasible. Examples of PPE used in industrial settings include safety goggles, gloves, earplugs, and steel-toed boots.
Selecting the Right PPE
When selecting PPE, it is essential to consider the specific hazards associated with each job and choose equipment that provides adequate protection without hindering the worker's ability to perform their tasks. It is also crucial to ensure that PPE fits properly and is comfortable to wear, as ill-fitting or uncomfortable equipment may not provide the desired level of protection.
Training Workers on the Proper Use of PPE
Workers must be trained on the proper use, care, and maintenance of PPE. This training should cover topics such as how to put on and take off the equipment, inspect the equipment for signs of wear or damage, and clean and store the equipment properly.
Regular Maintenance and Inspections
Regular maintenance and inspections ensure that machines operate safely and efficiently. Some critical aspects of a successful care and inspection program include:
Preventive Maintenance
Preventive maintenance involves performing regular service and upkeep on machines to prevent breakdowns and extend their useful life. This may include lubricating moving parts, replacing worn components, and cleaning filters. A well-planned preventive maintenance program can help prevent unexpected equipment failures and minimize downtime.
Routine Inspections
Routine inspections involve visually checking machines for signs of wear, damage, or potential hazards. Training personnel should conduct these inspections and cover areas such as machine guarding, safety interlocks, and emergency stop devices. Any issues identified during the review should be addressed promptly to prevent accidents and ensure safe operation.
Recordkeeping
Keeping accurate records of maintenance and inspection activities is essential for tracking the performance of machines and identifying trends or patterns that may indicate potential problems.
