Falling objects

An LTI is a lost time incident, mentioned earlier as an accident which causes one or more days away from work. A non-LTI injury does not result in time away from work. A near hit (often called a near miss) is an incident which causes no injury, but had the potential to do so (e.g. a falling object hitting the ground, but missing personnel). An example of an unsafe act would be a poorly secured ladder, where no incident occurs, but which potentially could have been the cause of an incident. 

Head protection is required against falling objects but also serves against heat, chemical splashes, or entanglement of hair in machinery. The appropriate standard is BS EN 397 (1995). 

Protection to be worn at all times unless there is no risk from falling objects or possibility of hitting the head against something... 

Aim to protect the health and safety of everyone in the workplace and ensure that adequate welfare facilities are provided. Covers e.g. general ventilation, temperature in indoor workplaces, lighting, cleanliness, space requirements, condition of floors and traffic routes, measures against falls/falling objects, washing facilities.

Impact sensitivity varies widely from one chemical to another. Since it is not possible to test many chemicals with wide sensitivity ranges by a conventional drop hammer test, we have begun the trial use of a drop ball tester which allows us to change the weight of falling objects over a wide range 101. ... 

The chemical release into a confined space is life threatening. High-pressure liquid, falling objects, and slippery surfaces in a confined space are all potential hazards. The limited space, inadequate ventilation and light, and excessive noise are also physical hazards that increase the confined space hazards. The chemical waste and useful chemicals are also life threatening.
