The Safety of Our Employees

Lonza wants every employee to return home safely and in good health at the end of their working day. 

Health and Safety of our workforce is a top priority. Any accident is one too many. We are convinced that accidents are avoidable and we commit to work in this direction with full strength. Our Vision 'Zero' - zero injuries, zero process incidents, zero distribution incidents and zero environmental incidents underlines our committment to safe and healthy workplaces, and is paramount to setting a clear and transparent top-down signal for safety at work.

Every employee is obliged to take on his or her fundamental and personal responsibility for safety and health at work.


At each site a safety committee supports the implementation and improvement of safety at work programs.

Corporate EHS Guidelines are developed in close collaboration with regional EHS experts. Their implementation at manufacturing sites and research and development centers is compulsory. It is the responsibility of line management at each site that they are implemented. Corporate EHS is auditing sites internally for EHS performance on the basis if the guidelines issued. Current guidelines cover:

  • EHS management system
  • Comprehensive process safety emergency/crisis management and incident reporting
  • Health surveillance
  • Limitation of occupational exposure to chemicals
  • Allocation of storage classes
  • Containment strategy
  • Hot work and safe work permitting
  • Confined space entry Lock out, tag out
  • Line breaking
  • High work and fall protection
  • Excavation, trenching and shoring
  • Contractor selection and evaluation
  • Supply chain security EHS Performance Reporting


Statistical Data

LTIFR  takes into account accident from Lonza full or temporary employees, as well as of externally hired employees under direct supervision of Lonza personnel. 

LTI frequency

To be able to achieve our 2020 goal of the injury rate of 0.6 or lower we intensify  further the global co-operation across all segments to embed “Vision Zero” in our safety culture. The common commitment to safe behavior of all employees working globally is paramount. Vision “Zero” is guiding our safe work practices, and gets high-level management attention from the Executive Committee.

Nevertheless our safety performance in 2015 could not meet the record of the previous year. The year 2015 was unsatisfactory and ended with a rate of 1.44. In addition, we incurred a severe process incident in March 2015 at our main plant in Switzerland in the course of which one of our employees lost his life.

Material Incidents and Severe Accidents

Despite a several-year trend of steadily improving safety performance, we are not immune to setbacks and to sad reminders of what is at stake. In March 2015 one of our employees tragically lost his life during a process incident at our Visp (CH) site. We have conducted an intense root-cause investigation and implemented vital new preventive measures. In addition, we have created a new, centralized process safety department, whose expertise will help keep our processes safe.

Other than the Visp site, none of Lonza’s sites reported any material incidents or breakdowns, nor were there any severe accidents or damage inflicted on the public or the environment in connection with the transportation of Lonza products and raw materials.
