Key Legal Responsibilities of Welding Contractors for Workplace Safety and Compliance in the Philippines

Welding activities are integral to a range of industries in the Philippines—from construction and shipbuilding to manufacturing and infrastructure projects. However, welding also carries inherent hazards that can endanger workers’ health and safety if not properly managed. Philippine laws and regulations therefore impose numerous responsibilities on welding contractors to ensure a safe and legally compliant working environment. Below is a comprehensive guide that covers all key legal duties, obligations, and considerations for welding contractors operating in the Philippines.

1. Legal and Regulatory Framework

Republic Act No. 11058 (RA 11058) – “An Act Strengthening Compliance with Occupational Safety and Health Standards and Providing Penalties for Violations Thereof”
- Enacted in 2018, RA 11058 underscores the legal mandate for all employers, contractors, and subcontractors to comply with occupational safety and health (OSH) standards.
- It details the general responsibilities for employers, including the provision of safe work conditions, adequate training, and personal protective equipment (PPE).
Department Order No. 198-18 (DO 198-18) – Implementing Rules and Regulations (IRR) of RA 11058
- This DOLE issuance provides the specific implementing guidelines.
- It explains procedures for OSH compliance, penalties for violations, requirements for safety officers, and the necessity of proper OSH programs.
Occupational Safety and Health Standards (OSHS)
- Initially promulgated in 1978 by the Department of Labor and Employment (DOLE), the OSHS has undergone revisions and updates.
- The OSHS provides detailed protocols on hazard control, safe operating procedures, accident reporting, and more. Contractors must align their safety policies with these standards.
Relevant DOLE Department Orders
- Beyond DO 198-18, DOLE occasionally issues memoranda and department orders that address specific hazards or industries. Welding contractors should monitor any new circulars or updates concerning welding operations, construction safety, and hazardous materials.
TESDA Requirements for Welders
- The Technical Education and Skills Development Authority (TESDA) sets competency standards for welders (e.g., NC II, NC III certificates). While these are individual certifications, contractors have an indirect obligation to ensure the welders they employ possess the necessary qualifications and expertise.
Fire Code of the Philippines (RA 9514)
- Welding poses fire and explosion risks; the Bureau of Fire Protection (BFP) mandates compliance with proper fire safety measures.
- This includes securing necessary permits for “hot work,” ensuring the presence of fire extinguishers, and adopting adequate fire prevention protocols at worksites.
Local Government and Building Code Requirements
- Depending on the jurisdiction, local governments may require additional clearances or permits for welding operations.
- The National Building Code of the Philippines (Presidential Decree 1096) may also impact the design and layout of sites where welding is performed, particularly regarding ventilation, emergency exits, and structural safety.

2. Key Legal Responsibilities of Welding Contractors

2.5. Hazard Control and Risk Management

Ventilation and Fume Control
- Welding fumes contain hazardous substances; contractors must ensure adequate ventilation or extraction systems, particularly in enclosed or confined spaces.
- Additional protective measures, such as respirators, may be required if ventilation alone is insufficient.
Fire Prevention and Control
- The Fire Code (RA 9514) mandates the proper storage of flammable materials, the availability of fire extinguishing equipment, and the clearance of combustible objects from the welding area.
- “Hot work” permits must be secured from the local fire authority for projects involving welding.
Signage and Warnings
- Clear signage indicating “Welding Area—Authorized Personnel Only” and “Wear PPE” must be posted.
- Hazard warnings and instructions must be in a language or format easily understood by all workers.

2.6. Record-Keeping and Reporting

Accident and Incident Reports
- All work-related injuries, illnesses, and near-misses must be documented accurately.
- Serious incidents must be reported to DOLE within prescribed timelines under DO 198-18.
