Thiết bị bảo hộ cá nhân I. GIỚI THIỆU Chương này có thể dùng để điều trị hợp lý rộng lớn nhưng không đầy đủ thiết bị bảo hộ cá nhân. Nó được thiết kế để cung cấp một cái nhìn tổng quan về chủ đề này trong bối cảnh của việc sử dụng phòng thí nghiệm bình thường. Khái niệm của các phòng thí nghiệm sẽ được mở rộng để bao gồm các nghiên cứu thực địa, nơi các công nhân thường tiếp xúc với chất độc hại như hóa chất nông nghiệp để các cuộc thảo luận thiết bị. | Furr A. Keith . PERSONAL PROTECTIVE EQUIPMENT CRC Handbook of Labrotory Safety Edited by A. Keith Furr . Boca Raton CRC Press LLC 2000 Chapter 6 PERSONAL PROTECTIVE EQUIPMENT I. INTRODUCTION This chapter is intended to be areasonably extensivebut not exhaustivetreatment ofpersonal protective equipment. It is designed to provide an overview of the topic in the context of normal laboratory usage. The concept of laboratories will be extended to include field studies where workers are often exposed to hazardous materials such as agricultural chemicals so that the protective equipment discussion will also apply to them. II. RESPIRATORY PROTECTION Respiratory protective devices rangeall the way from the simple soft felt mask which is often used to provide protection against nuisance levels of dusts and particulates to the selfcontained positive-pressure fully-enclosing suit which if properly matched to the antici-pated exposure offers total body and respiratory protection from the toxic substance involved. As will be noted in a later section on gloves and protective clothing there is no single material that will protect against all possible chemicals in the workplace so there is no universal material which will provide protection in all cases. Ifa laboratory is properly designed and operated with adequate ventilation andefficient fume hoods or other types of safety cabinets additional respiratory protection normally will not be needed for most procedures. However in the event of an accident or an unusual operation which cannot be performed in a hood orwhen working with highly toxic substances laboratory persons working with toxic materials should be included in a respiratory protection program managed by the institution or corporation. There are a few situations which should require the availability of respiratory protection immediately at hand. The selection of the proper respiratory protective device will depend upon a number of factors the most important of .
