PPE Testing


NON-RESPIRATORY PPE (PERSONAL PROTECTIVE EQUIPMENT) TESTING LABORATORY (NRTL)

INTRODUCTION :

Adequate protection of body is essential in order to ensure the safety of human life at work in every industry though the nature of protection varies from industry to industry and is dependent not only on the type of operation but also on the kind of hazard associated. Personal Protective Equipment (PPE) are always recommend for use in industry to protect the workmen against physical, chemical, and biological agents which possess hazard potentials of causing harmful health effects to the workers. Various engineering control method and technologies are generally applied to minimize the degree and intensity of such occupational hazards, but in case of certain industrial hazards, but in case of certain industrial situations, there is no choice but to recommend the use of PPE. The magnitude of use of PPE in industries, have increased in the recent years due to the growth of modern technologies and effective safety awareness programme.

It has been well recognized that the degree of protection provided by the PPE to the workers greatly depends upon their selection, use, and the extent of their performance in actual operation. The use of Personal Protective Equipment (PPE) by the employees in the factories under different situations is a statutory provision made under Sections 32, 35 and 36 of the Factories Act, 1948. The Bureau of Indian Standards (BIS) has brought out many standards on Personal Protective Equipment for protection of eyes, face, ears, feet, legs, hand, head, etc. in addition to guidelines for selection and use of such equipment. However, the testing facilities available in the few institutes in the country are not sufficient to ensure the quality of products as per the Bureau of Indian Standards.

Therefore ,the Central Labour Institute , Mumbai has set up to a Non-Respiratory Equipment Testing Laboratory (NRTL) to carry out Performance test for different types of PPE’s as per the standards laid down by the BIS . The laboratory is equipped with all the sophisticated equipment that are needed for testing of PPE. At present the laboratory undertakes testing of samples of PPE and issues performance test reports in regard to the quality of protective appliances.

    RESPIRATORY PPE (PERSONAL PROTECTIVE EQUIPMENT) TESTING LABORATORY (RTL)

    INTRODUCTION:

    Most of the chemicals that are used, handled, processed or manufactured in industries are harmful to the workers in varying degrees. These chemicals may be toxic, corrosive or carcinogenic and may cause health hazards through inhalation, ingestion or skin absorption. Technological measures are practiced in many industries to control toxic contaminants in work environment. However, there are situations when the use of respiratory devices becomes vital and essential.

    It has been observed from the Hand Book of Labour Statistics (1992), of Labour Bureau, Ministry of Labour, Government of India, Chandigarh/Shimla that every year more number of workers get exposed to the various types of chemicals and contract occupational diseases. Thus, PPE play an important role in safe-guarding the health of the industrial workers from various occupational diseases, provided they meet the requirements of the specified standards of BIS.

    AMENDMENT IN THE FACTORIES ACT:

    First Schedule {Section 2 (cb)} of the Factories (Amendment) Act, 1987 provides the list of 29 different industries involving hazardous processes Second Schedule (Section 41-F) lists the permissible levels of 117 toxic chemicals causing various occupational diseases by entering into body through the vital respiratory mode. In view of this, it is of foremost importance to use various respiratory PPE as the preventive measures against these toxic chemicals. Rule 81 of Model Rules under the Factories Act, 1948 (corrected upto 31.3.1987), Government of India, prescribes the use of various PPE.

    ACHIEVEMENTS:

    Disposable dust masks: A simple, inexpensive, comfortable and disposable type dust mask was developed by this Laboratory. It was made from low cost man-made fibers by the die-punch moulding technique. Developed masks were subjected to performance tests in accordance with the U.S. Bureau of Mines specifications. Extensive work was carried out on these masks to determine the performance parameters such as filtering efficiency, breathing resistance and mechanical strength. The complete know-how data was transferred to the National Research and Development Corporation (NRDC), New Delhi for its transmission to the industries for its commercial production.

    PRESENT TESTING FACILITIES :

    This Laboratory is equipped with the facilities to undertake the testing of Breathing Air of cylinders (SCBA) and Dust respirators / Dust masks, as per the Standard specifications laid down by the BIS. The equipment used for testing Respiratory personal protective equipment are procured and utilized as per the specifications mentioned in the Indian Standards.

    The division also conducts visits of participants from different industries, factories, colleges, institutes etc for demonstration of PPE’s and testing work carried out in the laboratory. In-Plant Training at the factory / industry etc. is conducted for creating awareness and spreading information about the PPE’s importance of wearing them, proper use, maintenance, etc. at work place, for the safety of workers.

    The division conducts study/surveys for the estimation of the compressed air quality at source, drawn from the compressor situated at the company/factory/ supplier’s premises
