Prevention before site work begins
Convention 167 was adopted in 1988 and establishes an international framework for construction safety and health. It covers building, civil engineering and erection and dismantling of prefabricated structures within its definitions and application conditions.
It binds ratifying States through the prescribed mechanisms. National legislation determines specific responsibilities and procedures. An international reference should not be confused with the particular legal arrangements governing a Spanish or Latin American construction project.
Coordination does not erase individual duties
Where several employers work simultaneously, the convention assigns coordination to the party exercising actual control or primary responsibility for overall site activities. A designated on-site party needs competence, authority and resources. Each employer retains duties towards its own workers.
This distinction helps explain construction project participants and preventive duties. A coordination meeting alone does not resolve an interface hazard. It must lead to decisions about incompatible activities, access, work sequencing and protection of affected people, with the resulting arrangements communicated to those carrying out the work.
Design, planning and changes
Designers and planners should consider the safety and health of construction workers. Recommendation 175 develops early preparation, selection of materials and working methods, and organisation of cooperation. It supplements the convention rather than replacing national technical requirements.
For example, an assembly decision may avoid later work in a difficult position. If the planned sequence changes, controls need review and communication to the employers involved. Keeping a plan that no longer describes actual execution leaves the risk introduced by that change unresolved.
Participation and workplace protection
The framework addresses safe conditions, information, training and participation rights. It includes action in serious and imminent danger and technical subjects such as scaffolds, lifting equipment, excavations, electricity and dangerous substances. These principles require technical development suited to each operation.
A useful review asks who decides, who implements and who verifies each measure. Documentation should reflect those roles without shifting all preventive responsibility onto individual workers. This entry does not calculate temporary structures or prescribe lifting manoeuvres. It organises the responsibility framework needed to prepare and supervise construction work.
