Real-Time Safety Risk Assessment Based on a Real-Time Location System for Hydropower Construction Sites

Table 1

Dynamic and static hazards and their associated activities on construction sites.

	Hazards description	Associated activity
Dynamic hazards	(1) Collision with or entrapment by a moving load due to its movement or detachment	Mechanical load handling.
	(2) Collision with or being ran over by heavy equipment or heavy goods vehicles	Work with heavy equipment or heavy-goods vehicles
	(3) Cuts, blunt trauma, and other injuries due to light equipment	Work with light equipment
	(4) Burns	Welding
	(5) Injury due to the impact of falling objects and projectiles	Manual, mechanical, or explosive demolition; shot-hole drilling before the blasting of a cut slope and the subsequent cleanup and field survey
	(6) Collision with or being ran over by vehicles unrelated to the construction work	Work in areas with traffic unrelated to construction work
	(7) Traffic accident	Transport of equipment and materials to the construction site
Static hazards	(1) Fall to lower levels	Work at heights or depths of more than 2 m
	(2) Direct or indirect electrical contact	Electrical work, work in proximity to power lines, and work with electrical equipment under wet conditions
	(3) Burns caused by fire or explosion due to a ruptured pipeline	Work close to fuel pipelines
	(4) Gas inhalation	Work near gas pipelines
	(5) Entrapment and subsequent suffocation due to a landslide	earthmoving, excavation, shafts, underground work, and tunnels
	(6) Particle projection and accidental explosion	Blasting for excavation, shafts, underground work, and tunnels
	(7) Decompression sickness	Work under hyperbaric conditions
	(8) Blows to upper and lower limbs	Manual load handling
	(9) Acute dust and toxin poisoning	Manual, mechanical, or explosive demolition of structures or buildings in general and of hospitals, factories, slaughterhouses, or any other place that may contain toxic substances
	(10) Suffocation or poisoning in confined spaces	Work in confined spaces
	(11) Drowning	Work in areas at risk of flooding
	(12) Structural risk or macrorisk	Complex operations or structures
