Risk assessment and Proposed Approach

Pursuant to article 3.5g of the Working Conditions Decree companies receiving containers must investigate whether employees who must open or enter containers, may be exposed to the dangers of suffocation, intoxication, poisoning or fire (or explosion).

Van Tienen Milieuadvies B.V. can support you in this. We can carry out a Risk Assessment (in Dutch RI & E) and we can prepare a Plan of Action or Proposed Approach. The Risk Inventory and Evaluation is performed by a Safety Expert and a Chemist. A Risk Inventory and Evaluation prepared by us fully meets the current regulations in the field of gases in containers, as recorded in the Working Conditions Legislation.

In order to categorize container streams it is important to map out the various types of goods as accurately as possible, at article and/or supplier’s level. This will enable us to provide overviews desired by the customer. We can provide a concise Excel file, but we can also provide complete graphical representations. Because of this it is no longer necessary for our customers to maintain a database for the container streams themselves. In many companies several employees are engaged in categorizing container streams and risk inventory and assessment. That is a job we can do for our customers, and, consequently, we can save our customers a lot of work and money (reduction of costs).

When making an inventory of the container streams our measuring method is based on the results of the container measurements and extensive FTIR-analysis.

Nationally, it is still common practice in many companies to conduct measurements on the basis of a standard list of common gases. Within the framework of a Risk Inventory & Evaluation that is not sufficient, because we frequently measure gases such as pentane, hexane and dichloromethane, that do not occur on any standard list. In our opinion a directed investigation must be conducted to determine which gases staff entering a container may be exposed to.

If a container stream is free of gas, to be determined on the basis of a number of measurements, we can consider doing random measurements, if necessary. It is also possible to examine a container stream in which structurally the same types of gas are detected specifically for the familiar dangers.

Consequently, proper Risk Inventory & Evaluation can lead to substantial savings in costs in the long run. In this respect for a well known Electronics Group we were able to reduce the number of measurements by 50 %, without compromising safety or regulatory compliance.
