Grading treatment method of toxic chemicals of petrochemical enterprise

Abstract

The invention discloses a grading treatment method of toxic chemicals of a petrochemical enterprise, and belongs to the technical field of dangerous chemical grading treatment. The grading treatment method of the toxic chemicals of the petrochemical enterprise includes: dividing the toxic chemicals into acute toxicity chemicals, corrosion and irritation chemicals, sensitization chemicals, carcinogenicity chemicals and diffusivity chemicals, selecting three hazard index points equal to 25, 45 and 65 as marking nodes of grading of the toxic chemicals by calculating hazard indexes of the toxic chemicals, and then dividing the toxic chemicals into slight hazard chemicals, moderate hazard chemicals, high hazard chemicals and extreme hazard chemicals, and thereby meeting the requirement of the petrochemical enterprise for improving toxicant safety management efficiency on the premise of not increasing management costs. The grading treatment method of the toxic chemicals of the petrochemical enterprise is provided with petrifaction characteristics, fully reflects a thought of managing the toxic chemicals by different levels and in differentiated mode, and simultaneously provides decision basis for further providing grading management measures.

Description

technical field [0001] The invention belongs to the technical field of classified treatment of hazardous chemicals, and in particular relates to a treatment method for chemical toxicity classification in petrochemical enterprises. Background technique [0002] In recent years, the implementation of classified supervision of occupational hazards has become an urgent need for the government and enterprises to supervise occupational hazards. In 1996, PetroChina Dalian Petrochemical Company classified 30 toxic work positions in the company according to the "Toxic Work Classification" (GB12331-90), which was the first beneficial attempt by a domestic enterprise to classify toxic substances; in 2009, Fudan University School of Public Health proposed a A new classification method for toxic operations, and applied index analysis method to carry out occupational hazard risk assessment for some operating positions of toxic operations such as benzene and toluene; in 2010, the State Adm...

Problems solved by technology

[0003] However, the existing chemical toxicity grading methods have many types of indicators, some indicators such as "actual hazard consequences and predictions" and "accumulation", and there are disadvantages such as difficult access to data support or inability to directly judge, which to a certain extent poses a threat to enterprises. Increased management difficulty and cost

In addition, with the reference standards of the published classification standards being replaced by new standards, the continuous increase of new toxic chemicals, and the deepening of research and understanding of original chemicals, the existing classification methods can no longer fully meet the current classification management of toxic workplaces. new needs
