Creation of Bureau Veritas
► 1828 : creation at Antwerp of the « Bureau de renseignements pour les assurances maritimes » by 3 marine insurers
► Aim : to keep underwriters informed of the premiums in use in various commercial centres and at the same time to provide« a detailed description of the good and bad qualities of vessels calling at the main ports of the Netherlands »

General precautions
► Read carefully the personal safety instructions which are available in the work instructions and the Mini Survey Handbook.
► The surveyor must be suitably dressed for the space to be inspected
► This includes shoes, gloves & hard hat. The shoes should not give rise to a spark.
► The surveyor should carry a suitable torch, depending on the space to be inspected, an explosion-proof torch may be required
13
General precautions
► Watch for :
� Deck openings open or unguarded
� Surveying below men working overhead or beneath loads being handled
� Surveys of tanks or compartments during ballasting or heavy lifting of cargoes
� Electric welding without proper eye protection
14
General precautions
► Watch for :
� Badly fixed, unsteady or unguarded scaffolding
� Timber of scaffolding in poor condition or overhanging
� Wooden hatch covers badly secured or missing
� Ladder rungs missing or in poor condition
� Decks, platforms etc., slippery or icy.
15
► Do not conduct surveys alone or when workers have d eparted
► Internal inspections, particular care when:
� Inadequate lighting
� Slippery surfaces
� Open manholes in stringer plates
� Corroded handrails & ladders
� Doubt about ventilation and atmosphere
General precautions
16
General precautions
► Engulfment Hazards
� Loose, granular material stored in holds or tanks, such as grain, sand, coal, or similar material can engulf and suffocate a worker.
� The loose material can crust or bridge over and break under the weight of a worker
18
Confined spaces
►Definitions *)
Enclosed space means a space which has any of the following characteristics:
1. limited openings for entry and exit;
2. inadequate ventilation; and
3. is not designed for continuous worker occupancy
*) Reference: IMO MSC89/25 Appendix 23
20
General precautions
► Spaces poor in oxygen include :
� Spaces that contain less than 20.8%
� Heavily corroded spaces : the corrosion process consumes O2
� Enclosed spaces partially filled with sea or fresh water experience a reduction in O2 & the possible generation of toxic gases.
� Void spaces, M/E crankcases, edible oil tanks, etc.
21
Confined spaces
► Dangerous spaces
� Note - associated areas are considered as dangerous spaces
� Gas free certificate - safe for access
� Date / time of last verification - usually checked every 3 hours, assuming normal ventilation
� The certificate should be valid for the duration of the survey
22
Confined spaces
► Toxic spaces
� Spaces designed to contain toxic material
� Loading areas also included as dangerous spaces
� The space must not be entered if breathing apparatus is required
� Special equipment for testing for toxic substances - Draeger tubes
� Testing for oxygen
23
Confined spaces
► Boilers
� Enter when both manholes have been opened
� After ventilation & cooling
� If other boilers are in service check that boiler is properly isolated on steam, water and smoke sides
• At least two valves between the boiler under survey and the boiler under steam
24
General precautions
► The surveyor must observe the safety requirements o f third parties (shipyard, terminal, owners, authority, etc .)
► Slightest dizziness or lack of balance is a warning & the surveyor should leave the compartment immediately
� Optimum oxygen level to be 20.8 to 21%
� Combustible gases less than 10% of the lower explosive limit.
� Toxins within acceptable limits
� Maximum hydrogen sulphide level 10ppm
� Maximum benzene level 10 ppm

Confined spaces
► Flammable atmospheres
� Two things make an atmosphere flammable: the oxygen in the air and a flammable gas, vapor or dust in the proper mixture
� Different gases have different flammable ranges. If a source of ignition is introduced into a space containing a flammable atmosphere, an explosion will result
� An oxygen enriched atmosphere (above 22%) will cause flammable materials, such as clothing or hair, to burn violently when ignited.
27
Confined spaces
► Over 50% of workers who die in confined spaces are attempting to rescue other workers
� Rescuers must be trained in and follow established emergency procedures and use appropriate equipment and techniques (lifelines, respiratory protection, standby persons, etc)
� Steps for safe rescue should be included in all confined space entry procedures.
� Unplanned rescue, such as when someone instinctively rushes in to help a downed co-worker, can easily result in a double fatality, or even multiple fatalities if there are more than one "rescuer"
•Remember, an unplanned rescue will probably be your last
28
Confined spaces
► Prior to enter a confined space, check :
� When opened & how long ventilated
� Ventilation arrangements and means of verifying atmosphere during the survey
� Whether surrounding compartments are full &, if so, with what
� Nature of last cargo, if applicable
� Condition of the compartment (ballast tk. Rust)
•On average, there are 200 deaths per year in the Ma rine Industry as a result of confined space entries
29
Never trust your senses to determine if the air in a confined space is safe !
You can not see or smell many toxic gases and vapours, nor can you determine the level of oxygen present.

30
Confined spaces
► Check the isolation of the compartment :
� IG lines blanked, valves closed & marked
� P/V lines blanked, valves closed & marked
� Cargo / ballast lines, at least 2 valves closed & marked
� Drainage / flushing of cargo pipe lines passing through the tank
� Adjacent compartments not filled with toxic material
� Heating coils shut off

► IACS - Confined space safe practise
► ISGOTT 5th edition – Chapter 10 Enclosed space entry
Confined spaces
33
Confined spaces
► Prior to enter a confined space, check :
� Safety & communication arrangements
• External to the compartment being surveyed
• Internal, during the survey
� Review the entry certificate / permit
• When was it issued and its validity (incl. times)
• By whom & when next verification will be made
� Tankers - ISGOTT regulations to be observed
• International safety guide for oil tankers & terminals
34
Check-list for entering confined spaces
► A check-list is available in the surveyors work ins tructions. Do not enter a confined space until you have consid ered every item of the check-list, as well as any other item o f concern, and have determined the space to be safe.
► The check-list covers the following topics :� Confirmation that you will be accompanied during entry
� Verification of testing equipment and qualification of testers
� Testing of the atmosphere for oxygen level, toxic or flammable gases
� Continuous monitoring of the atmosphere during survey
� Ventilation of the confined space
� Isolation of the confined space
� Use of adequate clothing and safety equipment
� Standby and rescue procedures
� Entry permit
•Remember, the final decision is yours. If you are n ot confident that the space is safe for entry, do not enter it.
