The objective of ventilating cargoes in category a) is to minimise the concentration of hazardous gases within the atmosphere of a ship's hold. Some of these cargoes - for instance certain types of ferrosilicon and coal - are listed in the IMDG code and/or in the IMO Code of Safe Practice for Solid Bulk Cargoes, with specific recommendations. In this article you will get to know about the shipboard ventilation system used on ship. Furthermore, the two system namely: high and low velocity has also been discussed in detail. Shipboard ventilation is a necessary action that needs to be carried in order to protect the cargo that is being taken on ship from spoiling.
Ventilation One definition for Ventilation can simply be – The process of continuously moving fresh air into a given area. This process is the best way to control heat as well as most atmospheric hazards found in a confined space. Effective ventilation fan or blower systems can provide a method of maintaining a .

As a result of such processes oxygen can be displaced, therefore making spaces oxygen deficient. To maintain safe and healthful conditions for workers, these hazards must be monitored and controlled through whatever means necessary, whichFile Size: 2MB.

Shipboard ventilation systems supply and remove air to/from spaces throughout the ship. In doing so, these systems control quality of breathing air and protect personnel and sensitive equipment from potentially hazardous airborne contaminants, fires, explosions, and excessive Size: KB.
The air intake should be placed in an area that will draw in fresh air only. Ventilation should be continuous where possible, because in many confined spaces the hazardous atmosphere will form again when the flow of air is stopped.
De-ballasting a tank does not guarantee a safe atmosphere. Testing is still required. VENTILATION OF HAZARDOUS AREAS DUE TO THE PRESENCE OF GAS hazardous areas for the presence of combustible dust.
Engineers from overseas consider that, if in an area may be presence of a potentially explosive atmosphere during normal operations, this is a dangerous area. The stay time of gas, its concentration and statistics are. The atmosphere in the space is monitored continuously. [29 CFR (b)(3)] Atmospheres at or above the upper explosive limit (UEL) are maintained.
[29 CFR (b)(3)] Respiratory protection and other appropriate PPE and clothing are provided in accordance with the PPE section of 29 CFR [29 CFR (b)(3)]. before you go back in. Dangerous atmospheres can develop without warning.
If tests indicate a dangerous atmosphere, you must NOT enter the space until it is thoroughly ventilated and subsequent tests indicate the air is safe to breathe. Ventilation and testing must be continued as long as you are in. • Division I is the most severe environment: the hazardous atmosphere is always or often present, or becomes present during frequent servicing/repair.
• Division II: the hazardous atmosphere is only available infrequently, for instance in the case of an accidental spill or the failure of a mechanical positive ventilation system. It includes. transferred to atmosphere or, on marine installations, to the sea through the ship’s hull.
The remaining radiated heat must be carried away by the ventilation system. A system for exhausting ventilation air from the engine room must be included in the ventilation system design.
Combustion Air Combustion air is discussed in. VENTILATION. Continuous ventilation Low hazard atmospheres Mechanical ventilation Natural ventilation.
STANDBY PERSONS. Low hazard atmosphere Moderate hazard atmosphere High hazard atmosphere, engulfment or entrapment. RESCUE. Provision of rescue services Equipment and training Notification equipment is selected.
Many hazardous atmospheres are Class I, Group D, or Class II, Group G. However, certain areas may involve other groups, particularly Class I, Groups B and C. Conformity with the National Electrical Code requires the use of fittings and enclosures approved for the specific hazardous gas or dust involved.
Ventilation - The How. This is pretty simple really. Drop your ventilation blower duct into the space and turn on the blower. After a period of time, test the space again for any hazards. If the space tests clean, you can enter the space. However, once the space is clean you are not permitted to turn off the ventilation blower.
Exhaust ventilation can be used to remove flammable and toxic fumes, vapors, and particulates from the space. Where mechanical ventilation is used in potentially flammable atmospheres, this equipment must be rated as explosion proof by Nationally Recognized Testing Labs (NRTL).
Make sure that supplied air is from a clean source and that the hazardous atmosphere is exhausted to safe areas. other hazardous aerosols. • Utilize explosion-proof mechanical ventilation rated by Nationally Recognized Testing Labs in potentially flammable atmospheres.
• Ensure that supplied-air is from a clean source and that the hazardous atmosphere is exhausted to a safe area, where the contaminated air cannot re-enter the air-supply system. Hazardous material screening and categorization under the Shipboard Hazardous Material Minimization Program and listing on the Ship Hazardous Material List (SHML) through SHML Feedback Reports (SFR).
Cleaning products considered for listing in the US Navy Surface Ship Authorized Chemical Products and Dispensing Systems Catalog (SA4-CAT).
Hazardous atmospheres The atmosphere in a confined space may be hazardous for several reasons. The air may have too little or too much oxygen. The atmosphere may be toxic or explosive. Pages 4–13 describe some of the dangers of hazardous atmospheres.
Confined spaces with hazardous atmospheres could also have some of the physical. Oxygen-Enriched Atmosphere: An atmosphere that contains percent or more oxygen by volume. Related Employment: Any employment performed as an incident to or in conjunction with ship repairing, shipbreaking, or shipbuilding work, including, but not restricted to, inspection, testing, and employment as.
Hazardous Atmospheres in Confined Spaces Name: _____ Date: _____ Multiple Choice (circle the correct answer): 1. In order for a confined space to be considered safe for workers, the ventilation must ensure that the atmosphere maintains: a.
An oxygen content between % and % b. A high number of toxic products and cargoes are found in shipyard employment. Additionally, many shipyard operations use toxic materials or produce toxic atmospheres. Because of the confined and enclosed nature of the spaces where these products are generally located, the hazard is increased.
