Webinars and workshops

Webinars and workshops are excellent start to introduce for staff and management to matters of health and safety relating to work inside shipping containers. Relevant topics can include aspects of toxicology, risk assessment, measurement instrumentation and strategies and, of course, ventilation procedures.

Consultative service contracts

To follow up your investment, Evaqvent can in addition to the technical service contracts, offer consultative service contracts that will provide on-going support as new questions and challenges arise. This ensure that you have access to our extensive know-how and experience. Our support would then only be a phone call or e-mail away.

Not sure if safe? Pre-ventilate!

Unless a container has been determined to be safe, that is having levels at or below established 8-hour occupational exposure limits, we recommend pre-ventilation before opening and entering. Our method of pre-ventilation lowers the arrival concentrations in most cases to 20% or less within one hour. This reduction, in combination with the natural ventilation during unstuffing with the open doors, should render the personal exposure less than 2% of arrival concentrations.

Pre-ventilation using the Evaqvent method is always done before the container doors are opened, thus, eliminating the risk of high peak exposure when opening an unventilated container. The only time the container doors needs to be temporarily opened is when the corner vents have been taped from the inside. This situation is easily determined by noting the lack of exhaust air from the turbine or by vacuum measurement in a vacuum port in the Evaqplate. To remedy the situation, the tape from the nearest vent is removed (if possible), the door closed and the Evaqplate attached to this cleared vent. Taping of vents from the inside should be discouraged and communicated upstream to the parties stuffing the container.

Consider the fast reaccumulation

Due to on-going emissions, reaccumulation is often rapid in ventilated containers. Pre-ventilation should be carried out immediately before the container is opened and can also be left running while working inside.
