Accident Types

An accident isn't just an event that can be lumped into one big category. In reality, there are many different types of accidents. Let's take a look at a partial list.

Safety Memo - The Accident Cascade
  • Struck-by: A person is forcefully struck by an object. The force of contact is provided by the object.
  • Struck-against: A person forcefully strikes an object. The person provides the force or energy.
  • Contact-by: Contact by a substance or material that, by its nature, is harmful and causes injury.
  • Contact-with: A person comes in contact with a harmful substance or material. The person initiates the contact.
  • Caught-on: A person or part of his/her clothing or equipment is caught on an object that is either moving or stationary. This may cause the person to lose his/her balance and fall, be pulled into a machine, or suffer some other harm.
  • Caught-in: A person or part of him/her is trapped, or otherwise caught in an opening or enclosure.
  • Caught-between: A person is crushed, pinched or otherwise caught between a moving and a stationary object, or between two moving objects.
  • Fall-to-same-surface: A person slips or trips and falls to the surface he or she is standing or walking on. This is the second most common accident causing injuries in the workplace.
  • Fall-to-below: A person slips or trips and falls to a level below the one he/she was walking or standing on. This is the third-most common accident in the workplace (NSC).
  • Overexertion: A person over-extends or strains himself/herself while performing work. This is the most common accident in the workplace (NSC).
  • Bodily reaction: Caused solely from stress imposed by free movement of the body or assumption of a strained or unnatural body position. A leading source of injury.
