Construction sites are dangerous even under the best of circumstances. Roadway accidents, slips and falls, being struck by an object, accidents due to machinery, equipment or tool use, or exposure to harmful substances are some of the causes of injury or death.

Individuals with a chronic disease or condition, and their caregivers, can help assess whether the course of the condition or disease - in view of ongoing therapies, treatment and time - is improving, stabilizing or deteriorating.

94% of traffic accidents are caused by driver error, intoxication, and other human factors. Impairment testing can detect impairment no matter the cause, including fatigue. A recent survey conducted by the NHTSA reported fatigued truck drivers are the main reason for crashes.

Manufacturing requires acute attention to detail and the precision of action to avoid accidents in potentially dangerous conditions. A typical US manufacturer can expect to lose approximately $1,000 per employee per year in fatigue-related lost productivity.

In 2019 there were 27 mining fatalities in the U.S. and more than 5,700 injuries. Impairment increases the risk of accidents associated with entrapment, falls , explosions, machinery, hauling, and hoisting. Impairment testing reduces risk and gives employers an early warning.

The number of concussions sustained by student athletes increased six-fold from 2003 to 2013 in males and 3.6-fold in female. Impairment testing is a quick inexpensive, “on-the-field” means to assess if the athlete should return to the field or have further testing.

Oil fields are inherently dangerous workplaces where precision of thought and movement matter. Workers need to be alert at all times. Some workers use stimulants such as methamphetamine and cocaine to help stay awake through shifts lasting up to 48 hours.

Utility companies face a wide range of significant safety challenges: confined spaces, heights, travel, electricity, harsh outdoor environments, large vehicles, heavy machinery, and long hours under emergency circumstances.
