Rekan milist,

Beberapa waktu yg lalu telah terjadi fatal accident di dalam confined space. Tujuh (7) orang tewas di Keppel Shipyard (Singapore) akibat explosion dalam Cargo Tank sebuah tanker. Dan dua (2) orang tewas di Sime Sembcorp Engineering (Malaysia) akibat keracunan gas dalam tank sebuah Topside yg sedang dibangun. Berikut mungkin yg jadi penyebabnya.

Five reasons people die in confined space

1. They don’t recognize a confined space.

A confined space has few ways in or out and they may be difficult to get into or out of. They are not intended to be occupied by human beings on a regular basis and they may contain a hazardous atmosphere or other recognized safety and health hazard.

2. They trust their senses.

We think that if a space looks safe, it is safe. But most hazardous atmospheres are invisible. You cannot see, taste or smell most toxic and deadly atmospheres.

3. They underestimate the danger.

Before you finish reading a simple eighteen-word sentence like this one, methane gas can knock you out.

Exposure to some organic vapors may not kill you until the next day. Before entering a confined space, the person supervising the crew going in should make sure of the following: the personnel entering the space is
knowledgeable of the hazards and have proper safety equipment; the volume is isolated, at atmospheric pressure and tagged; the monitoring requirements have been established and the area is properly posted.

4. They do not stay on guard.

Often, a person will forget that a hazard may develop after they have entered a space. Sometimes, the work you are doing inside the confined space causes the atmosphere to become deadly. If this is a possibility, testing for the space must be an ongoing process, not just something you do before someone enters.

5. They try to rescue other people.

It is human nature to help a person in trouble. But the sad fact is that untrained rescuers usually die along with the victim they are trying to save. Holding your breath is not enough protection in a confined space that
is filled with a hazardous vapor, is oxygen deficient, or is blanketed with smoke. Calling for help is the most
important thing you can do to save the life of a person who is unconscious in a confined space. Only if you have appropriate rescue equipment and personnel available should a rescue attempt be made.

Katanya, confined space itu :

mempunyai sesuatu yang berhubungan dengan atmosfir yang bersifat membahayakan, tidak punya tingkat kandungan oksigen yang cukup menyebabkan tenggelam not intended or design as normal place of work.

Ikutan nimbrung, karena saya aware dan kebetulan juga pernah ‘disulitkan’ dgn confined space ketika sedang menginspeksi suatu equipment.

Confined-space hazards can be grouped into the following categories:

1. oxygen-deficient atmospheres

2. flammable atmospheres

3. toxic atmospheres

4. Mechanical/physical hazards

Permit-required confined space has the following characteristics:

1. Contains or has a potential to contain a hazardous atmosphere

2. Contains a material that has the potential for engulfing an entrant

3. Has an internal configuration such that an entrant could be trapped

4. Contains any other recognized serious safety or health hazard, might include: fall hazards, unguarded machinery, extreme heat or cold, steam pipes or chemical lines, hazardous noise levels, electrical hazards, presence of asbestos, etc.

Confined space entry program should be normally as follow:

1. Identifying all confined spaces

2. Preventing un-authorized entry

3. The permit system

4. Planning the entry: data gathering, hazards identifying, ventilation, isolating the confined space, purging/cleaning, placement of warning signs, identifying personnel and necessary equipment

5. Conducting pre-entry training: identify the confined space and the reason(s) for entry, work detail, inform entrants of suspected hazards, identify isolation procedures, identify purging and/or ventilation procedures, identify all equipment needed, determine necessary PPE, establish communication, protect from external hazards, pre-plan rescue procedures.

6. Preparing the confined space for entry: place warning signs, tools, safety equipment, monitoring equipment, etc., isolate all mechanical and/or electrical hazards, purge/ventilate the confined space, test the atmosphere, test for flammable gases, test for toxic, assemble all personnel involved, review rescue procedures and notify the Dept Head that entry is commencing

7. Utilizing safety equipment

8. Atmospheric testing procedures

9. Confined space cleaning procedures

10. Rescue Procedures

Semoga bermanfaat untuk program2 zero accident.

Saya ingin menambahkan, satu hal penting lagi, bahwa ‘worker’ dan ‘permit issuer’ yang akan terlibat dalam pekerjaan confined space harus terlatih dan bersertifikat.

Untuk itu kami lampirkan paket ‘Safetyco Certified Inhouse Confined Space Entry Training – for Worker’, dan ‘Safetyco Certified Inhouse Confined Space Entry Training – for Permit Issuer’ untuk referensi rekan-rekan milis yth.

Hasil dari pelatihan ini akan mencetak pekerja-pekerja yang tahu dan mampu bekerja pada confined space secara aman, dan juga dapat melakukan rescue dengan cepat dan tepat apabila terjadi confined space incident.
