Overview
ISO 14877:2002 specifies the minimum requirements and test methods for protective clothing and gloves designed for abrasive blasting operations that use granular abrasives propelled by compressed air or mechanical means. This international standard ensures safety for workers involved in surface treatment, protecting them from hazards posed by abrasive materials and harmful substances generated during blasting. It also sets requirements for the proper integration of protective clothing with respiratory protective devices, ensuring comprehensive protection in high-risk environments.
This standard does not apply to clothing or gloves intended for steam blasting, jet blasting, or flame blasting operations.
Key Topics
ISO 14877:2002 addresses several critical aspects for manufacturers, suppliers, and users of protective clothing for abrasive blasting:
- Minimum Performance Requirements: Establishes specific mechanical resistance criteria including abrasion, tear, cut, and puncture resistance for both clothing and gloves.
- Protective Clothing Types:
- Type 1: Clothing independent of respiratory protection.
- Type 2: Clothing combined with suitable respiratory devices.
- Type 3: Dust-tight clothing, fully integrated with respiratory equipment.
- Material Quality: Ensures materials in contact with skin do not cause adverse effects and the clothing remains free from sharp edges or burrs.
- Testing Methods: Defines procedures for mechanical strength, flammability, care labelling, and resistance against abrasives.
- Marking and Manufacturer Information: Provides specifications for labeling, including pictograms and detailed usage instructions to enhance user safety.
- Compatibility with Respiratory Devices: Stipulates design and testing requirements for ensuring safe and effective connections between clothing and respiratory protection, especially for clothing types 2 and 3.
Applications
ISO 14877:2002 is vital across industries where abrasive blasting is used for cleaning, finishing, or surface preparation, including:
- Shipbuilding and Maintenance: Protection during hull cleaning and surface treatment.
- Metal Fabrication and Construction: Essential for operatives performing surface blasting of metals and concrete.
- Restoration and Renovation Projects: Protection for workers remediating historic structures or removing old coatings.
- Industrial Equipment Maintenance: Use in facilities requiring periodic abrasive cleaning of heavy equipment or infrastructure.
By following ISO 14877:2002, employers and manufacturers can:
- Reduce occupational injuries from high-speed abrasive impact and airborne contaminants.
- Meet regulatory compliance in occupational health and safety.
- Improve confidence in personal protective equipment (PPE) selection and purchasing.
- Ensure effective integration of respiratory and bodily protection.
