1.3 Occupational Safety and Health Standards (OSHS) Core Rules

Promulgated in 1978 pursuant to Article 162 of the Labor Code of the Philippines, the Occupational Safety and Health Standards (OSHS) serve as the foundational technical safety manual for all establishments in the Philippines. Comprising over 28 distinct numerical rules, the OSHS covers administrative mandates, industrial hygiene standards, personal protective equipment requirements, and machinery safety rules. This section evaluates the core administrative rules that every Safety Officer 2 (SO2) must master.


Framework of the 1978 OSH Standards

The OSHS was formulated to establish minimum standards of safety and health in workplaces to protect workers against the hazards of injury, sickness, or death. While technical rules (such as Rule 1070 for Environmental Occupational Health or Rule 1410 for Construction Safety) regulate specific operational physical hazards, Rules 1000 through 1050 establish the administrative spine governing compliance management.


Rule 1000: General Provisions & Duties

Rule 1000 establishes the legal duties of employers, workers, and administrative officers to maintain a safe working environment.

Duties of Employers under Rule 1005

  1. Furnish a place of employment free from recognized hazards that are causing or likely to cause death or serious physical harm.
  2. Comply with all technical rules of the OSHS and post mandatory safety notices.
  3. Provide protective equipment free of charge and instruct workers on safe operating procedures.

Duties of Workers under Rule 1005

  1. Cooperate with management and the Safety Officer in carrying out safety regulations.
  2. Report unsafe conditions, defective machinery, and work incidents immediately to the supervisor.
  3. Properly use all personal protective equipment provided by the employer.

Rule 1020: Mandatory Business Registration

Rule 1020 mandates that every covered establishment must formally register its business operations with the DOLE Regional Office having jurisdiction.

Registration Rules & Procedures

  • Timeline: Registration must be completed at least 30 days before commencing operations.
  • Official Form: Application is executed using Form DOLE-BWC-IP-3.
  • Re-registration Trigger: Re-registration is required upon any change in business name, ownership, location, or major operational expansion.
  • Validity: Registration under Rule 1020 is valid for the lifetime of the business, provided no structural modifications or ownership shifts occur.

Rule 1040: Health & Safety Committee (HSC)

Rule 1040 establishes the Health and Safety Committee (HSC) as the primary policy-making and advisory body on safety matters within every workplace. Every covered establishment must organize an HSC within 1 month after commencing operations.

HSC Organizational Structure & Composition

The structure of the Health and Safety Committee depends on the establishment's worker population and risk level:

Committee PositionWorkplace Type A (Over 400 workers or High Risk)Workplace Type B (100 to 400 workers)Workplace Type C (Less than 100 workers)
ChairmanWorks Manager or General ManagerManager / Assistant ManagerDepartment Head / Owner
Members2 Management Reps, 2 Worker Reps, Company Physician1 Management Rep, 1 Worker Rep, Company Nurse1 Management Rep, 1 Worker Rep, First Aider
SecretarySafety Officer (SO2 / SO3)Safety OfficerSafety Officer

Operational Mandates of the HSC

  1. Plan and execute educational safety programs for employees.
  2. Inspect the workplace monthly to detect hazards and recommend corrective actions.
  3. Conduct formal safety investigations following workplace accidents.
  4. Review and approve the establishment's Annual Workplace OSH Program.

Rule 1050: Notification & Keeping of Accident Records

Rule 1050 establishes mandatory procedures for recording, reporting, and analyzing work-related accidents and occupational illnesses.

1. 24-Hour Emergency Notification

In cases of work-related fatalities or catastrophic accidents (defined as injuries resulting in severe loss of limbs or hospitalization of 5 or more workers), the employer must notify the DOLE Regional Office within 24 hours using the fastest available communication channel (telephone, email, or online portal).

2. Mandatory Periodic Reports

  • Work Accident/Illness Report (WAIR - Form DOLE/BWC/HSD-IP-6): Incident-based report for disabling injuries, occupational illnesses, and dangerous occurrences. Must be submitted on or before the 20th day of the month following the date of occurrence. (The annual January 30 deadline applies to the AEDR, Form IP-6b, not the WAIR.) Fatalities and permanent total disabilities also require 24-hour notification to the DOLE Regional Office.

  • Annual Exposure Data Report (AEDR - Form DOLE/BWC/HSD-IP-6b): Annual summary of exposure hours and injury rates. Must be submitted on or before January 30 of the following year.

  • Annual Medical Report (AMR - Form DOLE/BWC/HSD/OH-47): Prepared by the Company Physician or Nurse, summarizing employee health surveillance data, annual physical exams, and occupational disease occurrences by January 30.


Mathematical Formulas for Injury Rates (FR & SR)

Safety Officers utilize standard statistical formulas mandated under Rule 1050 to measure workplace safety performance and benchmark progress.

1. Frequency Rate (FR)

Frequency Rate measures the total number of disabling (lost-time) injuries per 1,000,000 employee-hours worked.

Frequency Rate (FR)=Total Number of Disabling Injuries×1,000,000Total Employee-Hours Worked\text{Frequency Rate (FR)} = \frac{\text{Total Number of Disabling Injuries} \times 1,000,000}{\text{Total Employee-Hours Worked}}

2. Severity Rate (SR)

Severity Rate measures the total number of days lost (or charged due to permanent disability) per 1,000,000 employee-hours worked.

Severity Rate (SR)=Total Days Lost / Charged×1,000,000Total Employee-Hours Worked\text{Severity Rate (SR)} = \frac{\text{Total Days Lost / Charged} \times 1,000,000}{\text{Total Employee-Hours Worked}}

Standard Time Charges Table

Rule 1050 provides standard scheduled charges for fatal or permanent partial disabilities:

  • Death or Permanent Total Disability: 6,000 days charged.
  • Loss of Arm Above Elbow: 4,500 days charged.
  • Loss of Hand at Wrist: 3,000 days charged.
  • Loss of Thumb: 600 days charged.
