b) For existing elevators (National law)

BetrSichV (Operational Safety Directive)

- Abolish barriers to free trade in Europe

- Applicable to new installations only

- Member States are responsible for the health and safety of their people

- Only defines general essential safety requirements

- Harmonized standards must retain a non-binding status

- Risk assessment (ISO/TC 14798)

Fundamental issues of the Directive 95/16/EG

European Lifts Directive

... in compliance with the New & Global Approach:

Products must be submitted to a

Conformity Assessment Procedure

• There are several ways to demonstrate conformity either directly to essential requirements or to harmonized standards.

• The manufacturer has the choice to select one of the different procedures available.

• Passing the conformity assessment procedures is a prerequisite for being allowed affixing the CE marking.

a) For putting new elevators in operation (European law)

b) For existing elevators(National law)

BetrSichV (Operational Safety Directive)

German Codes

from 1999

Law on Trade & Occupation (§24 GewO)

National Elevator Safety Code (TRA)

Machinery Directive (89/382/EWG)

Equipment Safety Law (GSG)

European Lifts Directive (95/16/EC) (for new installations)

early 1990s

for decades

from 2003 Operational Safety Directive (BetrSichV) (for existing installations)

Simplification and summing-up of different directives on health & safety, covering• working tools & appliances• organisation of occupational health & safety • equipment & machinery requiring statutory inspection (9 directives)

Justification for the changes• uniform law on operational plant safety • essential safety requirements, as in European Directives

Further requirements• maintaining the same level of safety• high standards for accreditation of authorized inspection bodies• market surveillance

Operational Safety Directive

The employer is responsible for the Directive’s application (setting up of a labor protection management system).

The employer has to make a risk analysis:

1) To identify and classify all devices and installations

2) To rate and quantify the endangering effects

3) To define safety measures complying with the state-of-the-art

4) To verify the effectiveness of the measures

The Directive just specifies protective aims.

How to make a transition to a new national law?

How to overcome the original stipulations?

In principle, the applicable code is based on the valid code when putting the elevator into operation.

When new codes and standards are published the owner cannot be forced to upgrade the elevator.

The BetrSichV demands that the owner of existingolder elevators is aware of any deviation in safetycompared to the latest state-of-art.

The owner is encouraged to upgrade.

EN 81 Part 80: Rules for the improvement of safety ofexisting passenger and goods passenger lifts

SNEL (Safety Norm for Existing Lifts)

50% of existing elevators in Europe are more than 20 years old, having different safety standards

Users are expecting a uniform safety level at no risk

Standard defines 74 risks / risk potentials• Guideline and checklist to identify risks• Evaluate the risk potential (frequency and seriousness)• Define priority classes of risk profiles

Approval as an inspection body in Germany

a) Notified Bodyfor putting new elevators in operationin compliance to European Lifts Directive

b) Accredited Certification Bodyfor existing elevators in compliance with BetrSichV (Operational Safety Directive)

Both kinds of accreditation are executed by the German National Accreditation Body (ZLS)

Minimum Criteria on Notification of Inspection Bodies

• Competent, non-disciriminatory, transparent, neutral, independent• Professional integrity and technical competence• Personal requirements: education, experience and capabilities• Technical expert opinion regardless of external influence• Inspector's salary independent from number or result of inspection• Insurance coverage for third-party liability• Adequate quality assurance system• Official recognition by authority having jurisdiction• Collect and analyze findings for exchange of information (training)

Maximum permissible deceleration

The safety gear is the ultimate safety device!

Reliable safety gear testing is imperative!

Worst-case accidents do happen!

Reporting of accidents / incidents is a must!

Analysis / evaluation by independent body

Conclusion on digression:

In Germany all inspection bodies have to submit report (CEOC form) to a National organization.

Scarcely any reports are made public!

No comparison among European countries is existing.

Deceleration too low!

Conclusions

Innovations and new elevator technologies MRL elevators2 cars in 1 hoistwayelectronic controllers and transducersnew materials, ...

More stringent requirements regarding- documentation (ISO 9000)- liability- additional customer requests

Manufacturer’s own product content is decreasingMore subcontractors, also for installationThe core competence of the industry is getting slimmer

Effects on the elevator industry

Innovations and new elevator technologies will modify the inspection’s objectives:

· Inspectors need more advanced expertise

· Pure visual and functional testing is inadequate

· Contemporary inspection tools are required to …enhance technical know-how and skillsprovide electronic fingerprint findings:

- traceable results cannot be falsified- prevent doing a personal favor

increasing competitivenessdemonstrate code compliance

Effects on elevator inspectors

Consequences of a contemporary codeSpecifies general safety requirements onlyRisk analysis in case of deviations

Future requirements include Strict safety aspects + quality issues!Traceable electronic documentationFully electronic business processes to - reduce administrative efforts / costs - increase customer loyalty / satisfactionEvidence to lower product liability

Enhanced benefits for all partners

A modern elevator inspection will become more important
