Taint Control
61.
| (1) | Before loading containers into rows previously used for the carriage of products which give off odorous gas, the ship's crew shall ensure that all traces of the tainting gas are removed. |
| (2) | The ship's crew shall also ensure that no fumes, either from deck cargo or exhaust pipes etc., are permitted to be drawn into the fresh air ventilating ducts. |

CO2 and Ventilation

| (1) | All fresh products that produce CO2 through respiration shall be ventilated at a rate that will maintain the CO2 level below 1% in the ship's hold or container. |
| (2) | The rate of fresh air introduction shall be one air change every two hours on the basis of the empty volume of the ship's hold or containers, and the actual rate shall be determined from measurements of the CO2 concentration in the return air ducts. |
| (3) | In view of the adverse effects thereof on temperature and humidity, excessive intake of fresh air shall be avoided. |
| (4) | Continuous air ventilation with partially opened vents shall be preferred to intermittent ventilation with vents fully open. |
