Overview

SIST EN 791:2000/kprA2:2008 is a European safety standard specifically focused on drill rigs used in construction and related industries. Developed by the European Committee for Standardization (CEN) under Technical Committee CEN/TC 151, this standard provides updated safety requirements and guidelines to improve operator safety and machinery reliability. The amendment A2, issued in 2008, introduces key modifications related to operator positioning, equipment markings, and operator instructions, aligning with essential requirements of EU Directives 98/37/EC and 2006/42/EC on machinery safety.

This standard is integral for manufacturers, operators, and regulators involved with drilling machines, ensuring compliance with European safety regulations and contributing to safer working environments.

Key Topics

• Operator Position Noise Limits: The amendment lowers the permissible noise exposure level at the operator's position from 85 dB(A) to 80 dB(A), reflecting increased emphasis on hearing protection and operator comfort.
• Marking and Data Plate Requirements: The data plate on drill rigs and associated equipment (such as winches and movable platforms) must now include:
  • Manufacturer’s full business name and address
  • Machinery designation
  • Where applicable, maximum persons permitted and maximum working load on movable platforms
• Operator Instructions: Enhanced instructions must specify sound emission levels using A-weighted emission sound pressure level, and provide information on whole body vibration acceleration-highlighting exposure levels if exceeding 0.5 m/s².
• Harmonization with EU Machinery Directives: Annexes ZA and ZB inform on the relationship with EU Directive 98/37/EC (amended by 98/79/EC) and Directive 2006/42/EC, ensuring standardized safety across member states and facilitating CE marking.

Applications

SIST EN 791:2000/kprA2:2008 applies primarily to drill rigs used in construction, civil engineering, and geological exploration. It serves various stakeholders including:

• Manufacturers: To design and label drill rigs that meet stringent EU safety and health protection requirements.
• Operators: To ensure the machinery is used safely with clear guidance on noise exposure and vibration risks.
• Safety Inspectors and Regulators: To evaluate machinery compliance during inspections, preventing workplace accidents.
• CE Marking Authorities: To verify conformity of drill rigs with EU machinery directives for market authorization.

This standard supports improving technology design related to operator positioning, acoustic and vibration safety, and clear equipment identification to reduce hazards in drilling operations.

Related Standards

When working with SIST EN 791:2000/kprA2:2008, consider additional standards and directives that govern safety and performance in machinery, including:

• EU Directive 2006/42/EC on Machinery Safety: Covers general health and safety requirements for machinery placed on the European market.
• EN ISO 11201: For noise emission measurement methods applicable to drilling machines.
• EN 12096: Pertains to vibration measurement and evaluation relevant when assessing whole body vibration on operators.
• Other CEN TC 151 Standards: Related to construction equipment safety and building material machinery harmonization.

Compliance with EN 791 and its amendments enhances safety culture and risk management in construction drilling, promoting international harmonization of safety standards for drill rigs.
