Reviewing real incidents can help determine if your work unit needs refresher training or improved procedures. The following examples are part two in illustrating common hazards and the importance of following safe work practices.

COUNTERWEIGHT CONCUSSION

An employee suffered a head concussion after standing too close to a Gradall while it was operating. The equipment’s rear counterweight extended into traffic on a two-lane road during ditching work, creating a hazard for both vehicles and nearby employees on foot. Injuries can also occur from the swing radius of backhoe buckets. In this incident, the employee assumed the operator could see him, but no positive eye contact was made.

Lesson Learned: Always stay clear of operating equipment. Maintain awareness of swing radii and counterweights, and never assume the operator can see you without making positive eye contact.

FORGOTTEN TIMER

A treatment plant operator was working on a motor with attached fan blades when the motor unexpectedly turned on. The operator had either forgotten or was unaware that the motor was on a timer, and the circuit had not been de-energized. As a result, several fingertips were amputated.

Lesson Learned: Always follow proper lockout/tagout procedures, verify that all energy sources are de-energized, and check for automatic controls or timers before performing maintenance.

HYDRAULIC HOSE HAZARD

A mechanic developed dermatitis over his entire body after replacing a blown hydraulic hose. Residual oil from the damaged fittings dripped onto his skin, causing a severe rash.

Lesson Learned: Always handle chemicals, oils, and fluids with care—even those you believe are harmless. Use appropriate personal protective equipment, and have a current Material Safety Data Sheet (MSDS) available so medical providers can respond effectively in the event of exposure.

MOWING MISHAP

During mowing operations in tandem, employees have been struck by flying objects when following too closely. Hazards have included small stones and even steel reinforcing rods. Fortunately, no fatalities have been reported, but injuries do occur each season.

Lesson Learned: Maintain a safe distance when mowing in tandem. Awareness of your partner’s position and proper spacing can prevent injuries from flying debris.
