Angle grinders are one of the most dangerous tools in any workplace. Most angle grinder injuries are from metal particles lodging in the operator's eye. However the most serious injuries are from kick-back, where the disc is thrust back violently towards the operator.
Discs can shatter or explode, sending pieces flying in all directions.
Because angle grinders are designed for grinding and not for cutting, the use of cutting discs with angle grinders exposes operators to even greater risks. It is the responsibility of the employer to provide and maintain a safe working environment and safe work procedures. The employer must also provide information, instruction, training and supervision to enable employees to work safely. Employees must follow any instruction and training provided, and must point out hazards to their supervisor. Employees also have a responsibility to take reasonable care to ensure their own safety and health, and to avoid adversely affecting the safety or health of others through any act or omission at work.
