Occupational Safety, Health and Environment in Telecom
What this domain covers
Hazards specific to telecom work - live electrical panels, antenna RF fields, towers and ladders, laser light, battery acid and glass fibre - plus environmental rules for e-waste and energy use.
Core rules
- Work at height: full-body harness with the dorsal D-ring anchored above shoulder level, helmet with chin strap, and a permit to work. Never anchor to a cable tray or an antenna stay.
- Electrical: isolate, lock out and tag out, test dead, then earth. Use CO2 or dry powder on live electrical fires - never water.
- RF: do not stand in the main beam of a live antenna; India's DoT exposure norms are one-tenth of the ICNIRP reference levels. Power down before climbing near radiating panels.
- Laser and fibre: never look into a fibre or connector; treat it as a laser hazard and put bare fibre shards in a sealed container, since they cause invisible eye and skin injury.
- Battery rooms: acid-resistant apron, goggles and gloves; add acid to water, never water to acid; no sparks or flames.
- Environment: e-waste rules with extended producer responsibility, lead-acid battery buy-back, segregation of scrap fibre and packaging, solar or hybrid BTS and free cooling to cut diesel use.
Worked example
A worker uses a 2 m lanyard with 1 m deceleration distance; the worker is 1.8 m tall and 0.5 m safety clearance is required. Minimum anchor height above the walking surface = 2 + 1 + 1.8 + 0.5 = 5.3 m. Reasoning: the anchor must arrest the fall before the feet reach the ground or the next lower level.
Traps
- Wearing the harness loosely or clipping to a weak point.
- Using water on an electrical fire.
- Assuming an antenna radiates only forwards - side and back lobes exist.
- Storing fibre offcuts in an open bin.
