Dust Hazardous Area Installation and Inspection Course
| Goal |
 |
To enhance the level of knowledge and understanding regarding the standards, regulations, best practices, and inspection techniques for electrical equipment utilized in potentially flammable or explosive dust atmospheres, in order to increase safety awareness and practices |
| Examination Details |
| Duration |
Two days |
| Skill Level Required |
The course is designed primarily for personnel with an electrical background. A working knowledge and experience of electrical installation and inspection is required. |
| Brief Description |
The course is intended to impart an awareness of the industrial standards relating to the construction, proper installation, and inspection of electrical/instrument equipment which may be exposed to potentially flammable or explosive dust atmospheres. The first day of the course looks at electrical/instrument equipment, which may be exposed to a combustible dust. The second day provides assessments, which may result in the award of competency certificate.
