If a certain hazard cannot be eliminated or substituted, the next best option is to use engineering controls.

Engineering controls offer protection to workers by isolating them from hazards that can lead to injuries.

When considering this option, explore choices that will make the workplace less dangerous for your workers, as you are unable to eliminate the hazard itself. This includes adding guards to machines with dangerous moving parts to safeguard arms, hands, or fingers from injury. Engineering controls can also mean placing barriers, such as a cage, around hazardous machinery, so only trained workers have access.

Could an emergency stop be added to the equipment? Can a trigger grip be added that must be held to keep the machine running, so it stops the instant the worker lets go? Can handles be added to boxes to protect fingers?

Engineering controls are a great way to reduce the risk of hand injuries when substitution and elimination is not an option. For successful adoption, however, workers still need to be aware of the risks and hazards surrounding them, especially if working around or with hazardous machinery. This is where our next step in the hierarchy becomes important.

Administrative controls include things like operation-specific regulations, work schedules that reduce exposure to hazardous tasks, and systems that increase workers’ hazard awareness. As such, administrative controls cover an exhaustive list of possibilities, including, but not limited to:

• Warning signs, training programs, and safety checklists
• Visual guides for safe work procedures or standard operating procedures
• Easy access to PPE such as self-serve vending machines on worksites
• Emergency wash stations for chemical exposure
• Job-rotation schedules that limit hazard exposure
• Break schedules to improve workers’ concentration
• Ensuring proper maintenance of equipment and tools
• Supervisory oversight and regular safety inspections
• Practicing emergency response procedures
  Maintaining well-organized and clean workspaces

When considering this option, it is important to note that the value of this control is truly realized when implemented in conjunction with other measures. For instance, although you may substitute a more dangerous machine with a less hazardous one, the risk of injury is still present. Proper training, procedures, and guidelines on how to use the new less hazardous machine is necessary to avoid injuries. Similarly, for tasks where gloves are mandatory, the right type of gloves must be accessible and must be required to be worn at the appropriate time. All these are administrative controls are integral to the success of creating a safer workplace.

At the bottom of the hierarchy, is your last line of defense, which is PPE.

Why is PPE at the bottom of the hierarchy of controls? Aren’t gloves, sleeves, and other PPE important to protect workers from the risk of hazards? The answer is not a simple yes or no.

PPE is considered the final shield when all other shields have failed. Safety managers and workers often forget to consider the other important control measures discussed above when they rely solely on PPE. This asks more of their PPE, because hazards are higher and they’re fighting more hazards than they need to.

When we take a holistic approach that addresses gaps in all safety controls—not just PPE—there are less hazards for safety gloves to fight. This often means increased productivity and lower costs, because there are fewer and less extreme hazards in the workplace. For example, if a potentially dangerous machine already has adequate safeguards to protect its operators from cut injuries, workers may be able to complete the same tasks using less expensive, lower cut level gloves more confidently and efficiently, and without the fear of getting seriously injured.
