Hazardous-Area Guide: Safety in Hazardous Zones ¦ METTLER TOLEDO

How to Weigh Safely
in Hazardous Areas


Edition 2 of our Hazardous-Area Competence Guide

Safety is crucial if you operate in potentially explosive environments,
and careful selection of weighing solutions to meet specific process
requirements and regulations can be a challenging task for manufacturers
that work within hazardous areas.

The second edition of our Hazardous Area Guide details how to avoid dangerous
situations with compliant equipment and provides illustrated recommendations
for correct installation and maintenance.

The guide has been recently updated and is currently only available in English.

7 Ways to Ensure Safety in Hazardous Area


Weighing equipment intended for use in hazardous areas must comply with extensive regulations, feature approved protection methods and be installed and maintained correctly to ensure safe operations. With our free guide, learn how to:

  • Avoid safety incidents
  • Stay compliant
  • Correctly install equipment
  • Prevent explosions
  • Properly mark equipment
  • And more!



Every year in the news there seems to be a major incident resulting from an accident in a hazardous area. Most of these unfortunate incidents could have
been prevented with a measure of safety competence, better planning and
the right equipment. While well-meaning companies can make mistakes, in hazardous areas, those mistakes can come at a high price.

How can I avoid safety incidents?

The key to avoiding these safety incidents lies in preparation, regulatory-standards knowledge and careful selection of the right equipment for hazardous-zone operation. Identifying the right equipment that can deliver both workplace safety and accurate measurements can be a challenging task for manufacturers. However, it is essential for a safe and reliable operation that limits potential danger to employees and capital.

How can I ensure equipment compliance in hazardous zones?

Our guide “Competence for Hazardous-Area Safety” explains how to avoid dangerous situations in hazardous areas with compliant equipment, and it offers a comprehensive explanation of standards and regulations. It also explains how to correctly install and maintain equipment in hazardous areas and offers examples of hazardous-area weighing systems.

How can I prevent an explosion?

An explosive atmosphere is a mixture of air and combustible material in form of gases, vapors, mists or dusts. Learn how to avoid sufficient energy output for ignition to avoid dangerous combustion and the chain-reactions they can precipitate.

How do you define hazardous area classifications?

Area classification is the method of analyzing and classifying the environment where explosive atmospheres may occur to facilitate proper electrical equipment selection and allow preparation of safety procedures. Learn the various categorization methods and how to apply them.

How do I ensure safety around electrical equipment?

The basic safety concept of ignition protection is to eliminate the simultaneous existence of possible ignition sources. The method of equipment protection will depend on the degree of safety needed for your hazardous area. Equipment markings are also covered so you can identify equipment with appropriate safety features.
