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


Tanggapan 2 : Hasanuddin

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
