Work environment

Gas fitters typically work 40 hours per week when working full time. However, full-time work may be seasonal. Gas fitters may have to work longer hours in good weather conditions or in order to meet project deadlines. In addition to their regular work, some gas fitters may work on an on-call basis responding to emergencies. Gas fitters generally work independently.

Gas fitters may work outdoors and be exposed to varying weather conditions. Work environments may be noisy and dirty. Workers may also be required to stand for long periods of time.

Gas fitters must be physically fit and be able to work in tight spaces. Work may be done at heights on ladders and scaffolding, so potential falls from heights pose a risk. Gas fitters work with explosive gas and must follow strict safety regulations. These workers receive safety training and wear special safety equipment to protect them from injury.

Insights from industry

Average annual growth is projected to be slow, however, some openings are expected to result from retirements.

Future demand for workers will depend on growth in the Construction and Utilities industries. Construction activity is sensitive to factors such as interest rates, population growth and the cost of materials.

Some work opportunities should be available because gas fitters are needed to install gas systems within new and renovated buildings and to work on development of new utility pipelines.
