OSH Legislation, Guidelines and Standards • EU-directives concern safety, health and welfare of employees • For the Netherlands they are included in: • Law on working conditions (“Arbo-wet”) • Implementation of the law on working conditions (“Arbo-besluit”) • Legislation concerning Working Conditions (“Arbo-regeling”) • Guidelines for Working Conditions Including Standards (“Arbo-beleidsregels”)
Netherlands resources onOSH Legislation & Guidelines • Arbo-informatiebladen • Arbo-themacahiers (only available in Dutch)

OSH in New, Renovated and Existing Buildings for Professional Use
A lot of information is available, so why do so many problems occur??
Causes of problems (1) • Design phase • Building regulations OSH regulations !! • Little attention for OSH • OSH is often considered a luxury and is consequently subject to budget cuts
Causes of problems (2) • Design phase • Design influences safety during building phase and maintenance • Maintenance is often overlooked • Aesthetics is preferred over functionality
Causes of problems (3) • During use • Rooms used in an different way than planned • Wrong use of building / installations • Not sufficient maintenance • Ageing of the building • Changing insights
Building code (“Bouwbesluit”) • Refers to new and existing buildings • Implements minimal safety, health and usefulness requirements OSH code (“Arbobesluit”) • Refers to new and existing working environments • Optimal OSH (working conditions) for workers and others involved
Building code (“Bouwbesluit”) • Commissioner / owner responsible • Performance requirements, seldom technical means OSH code (“Arbobesluit”) • Employer responsible • Optimization of OSH, seldom minimal standards
Building code (“Bouwbesluit”) • Ministry: Housing (VROM) • Supervising organisation: Community administration (Fire department, Building inspectorate) OSH code (“Arbobesluit”) • Ministry: Social Affairs and Employment (SZW) • Supervising organisation: OSH inspectorate (“Arbeidsinspectie”)
An example In the Netherlands approximately 50% of the office workers experience insufficient or bad indoor air quality Source: AI-blad 7 “Kantoren”, SDU, 2e druk, 2000
Causes of indoor discomfort in offices • 50% organisation and behaviour • wrong use of building / building services • insufficient or wrong maintenance • 50% bad design • wrongly designed building services • wrongly chosen building and finishing materials Source: AI-blad 7 “Kantoren”, SDU, 2e druk, 2000
DONT’S in problem solving • Immediately think about solutions • Aim at a quick fix • Make things worse • Perform one rebuilding after another
DO’S in problem solving • Objectify complaints • Try to find the complaint behind the complaint • Registration of complaints • OSH is sometimes misused • Thorough systematic investigation • Enquire with the occupants • Consult experts
OSH Risk Management Process • Thorough investigation of risks and possible solutions • Prioritization • Construction of an improvement program with timetable • Implementing the improvement program • If necessary repeat (1) to (4)
OSH Prioritization • High: immediate danger • Medium: possible exposure or detriment after prolonged exposure • Low: possible but unlikely situations
Prioritization by Housing Services* TU/e • Safety / health • Legislation / standards • Research / education • Resulting damage • Aesthetics / comfort * Dienst Huisvesting
Subjects Lay-out of working places (*) Hazardous chemicals / biological agents / airborne dust Physical factors (*) Machinery and equipment / specific tasks Safety and health signs * See next slides
Lay-out of working places (1) • General regulations: order and neatness, hygiene • Provisions for emergency situations • Effective working places
Lay-out of working places (2) • Lay-out requirements • VDU work / sedentary work • Recreational facilities and other provisions
Physical factors • Indoor climate including ventilation • Lighting and daylight • No view requirement anymore • Daylight is obligatory in most cases • Noise and sound
Why bother? Good working conditions: conditions allowing for optimal output of workers and thus contributing to the economic aim of the organisation they are a member of
Improvements afterwards=Suboptimal results at a multiple of the costs
