Trouble lights are handy, but they must be used with caution. Always follow the manufacturer's instructions and keep the following safety tips in mind:

• Look for the CSA International certification mark. This shows that the unit complies with recognized safety standards.
• Use trouble lights only in the locations for which they are intended.
• Do not use trouble lights where there is a risk of contact with gasoline or other flammable liquids or vapours.
• In explosive atmospheres (e.g. where there is a high concentration of flammable dust, liquids or vapours), only use units that are specifically marked for use in hazardous locations. In a service garage, the area less than 50 mm (2 inches) above ground is considered to be a hazardous location.
• Trouble lights are not intended as permanent light sources. Do not use them for prolonged periods.
