Seafarer Medical Standards and ILO Guidelines on Hearing Impairment

The maritime industry is inherently hazardous, demanding peak physical condition from those who man the world’s vessels. Among the various medical criteria, auditory fitness is paramount—not merely for personal health, but for the safety of the ship, its crew, and the marine environment. In the Philippines, the world’s leading provider of seafarers, the intersection of international standards and local labor laws creates a complex legal landscape regarding hearing impairment.


The International Framework: ILO and IMO Standards

The foundational standards for seafarer health are dictated by the International Labour Organization (ILO) and the International Maritime Organization (IMO). Specifically, the Guidelines on the Medical Examination of Seafarers, revised in collaboration between these two bodies, provide the technical baseline for hearing requirements.

Under the Maritime Labour Convention, 2006 (MLC 2006), every seafarer must hold a valid medical certificate. The ILO/IMO guidelines specify that:

  • Communication is Key: Seafarers must be able to hear warning signals, alarms, and oral commands.
  • Thresholds: Generally, a seafarer is expected to have no hearing loss greater than 30 dB (unaided) in the better ear and 40 dB (unaided) in the worse ear at the frequencies of 500, 1000, 2000, and 3000 Hz.
  • Speech Discrimination: For those in deck and engine departments, the ability to understand speech in noisy environments is a critical "fit for duty" criterion.

The Philippine Regulatory Landscape

The Philippines domesticates these international standards through the Department of Health (DOH) and the Department of Migrant Workers (DMW) (formerly POEA).

1. DOH Administrative Order No. 2007-0025

This is the primary regulation governing the medical examination of seafarers in the Philippines. It adopts the ILO/IMO standards, requiring Pre-Employment Medical Examinations (PEME) to be conducted by DOH-accredited clinics. If a seafarer fails the pure-tone audiometry test within the prescribed decibel limits, they are often declared "Unfit for Sea Duty."

2. The POEA Standard Employment Contract (POEA-SEC)

The POEA-SEC is the governing document for Filipino seafarers' rights and benefits. Under Section 20 (A), the employer is liable for disability benefits if the seafarer suffers a work-related injury or illness during the term of the contract.

Hearing Impairment Category Disability Grade (Philippine Law)
Total deafness of both ears Grade 3
Total deafness of one ear Grade 11
Loss of two-thirds of hearing in one ear Grade 12
Loss of one-third of hearing in one ear Grade 13

Jurisprudential Trends: The "Total and Permanent" Doctrine

In Philippine maritime law, a medical "Grade 3" or "Grade 11" classification does not always tell the whole story. The Supreme Court of the Philippines has consistently ruled that disability is not measured by the loss of a body part, but by the loss of earning capacity.

  • The 120/240-Day Rule: If a seafarer’s hearing impairment prevents them from performing their usual work for more than 120 days (extendable to 240 days under specific conditions), the disability may be legally classified as total and permanent, regardless of the "Grade" assigned by the company-designated physician.
  • Work-Relatedness: To claim benefits, the seafarer must prove that the hearing loss was "work-related." In the engine room, constant exposure to high-decibel machinery (often exceeding 85-90 dB) makes "noise-induced hearing loss" (NIHL) a compensable occupational disease.

Practical Challenges in Legal Practice

The legal battle often centers on the PEME vs. the Post-Employment Medical Examination. Employers frequently argue that if a seafarer passed the PEME, any subsequent hearing loss must be pre-existing or non-work-related. However, the courts often apply the "Theory of Aggravation," where if the work conditions worsened a pre-existing condition, the employer remains liable.

Furthermore, the use of hearing aids is a contentious point. While ILO guidelines allow for hearing aids in certain "non-safety critical" roles, the Philippine DOH standards are much stricter for deck and engine officers. If a seafarer requires a hearing aid to pass the threshold, they are frequently deemed unfit for the rigorous demands of international seafaring.


Summary of Legal Imperatives

For a hearing impairment claim to succeed in the Philippine jurisdiction:

  1. Timely Reporting: The seafarer must report the injury or symptoms within three days of repatriation (the "three-day mandatory reporting rule").
  2. Causality: There must be a reasonable link between the noisy environment of the vessel and the auditory deficit.
  3. Conflict of Opinions: If the company doctor and the seafarer's personal doctor disagree, a Third Doctor must be jointly appointed, whose decision shall be final and binding.
