Evaluation of Chemical Glove Permeation Breakthrough Time on Biocide Glutaraldehyde Injection at PT. X Upstream Oil and Gas Production Facility

Abstract

Microbiological contamination using biocide glutaraldehyde is one of the applications to maintain the integrity of pipelines and vessels in oil and gas production. PT. X’s data on the recording of occupational illness shows an incident that occurred in 2019 due to chemical mishandling. The incident resulted in an inappropriate selection of chemical gloves and caused seven cases of irritant contact dermatitis in workers who injected biocide containing glutaraldehyde. The purpose of this study is to evaluate permeation breakthrough time on three types of glove materials used in the glutaraldehyde biocide injection process. Data taken from replacement gloves for workers who carry out the glutaraldehyde injection process, technical data on three types of gloves used in production: butyl rubber with Viton® outer layer, 100% butyl rubber, and neoprene. Simulation calculated using NIOSH permeation calculator V.3.0.0. Result from technical data for butyl rubber with Viton®, butyl rubber BT >480 minutes, and ND for Neoprene. BT field used, butyl rubber with Viton®, butyl rubber 240 minutes, and neoprene 45 minutes. Based on simulation, open-loop BDT 4.6 minutes, SBT 4.83 μg/cm2/min, SSPR 661.648 μg/cm2/min, CP 1089.67, 4108.64 and 7369.79 μg/cm2; permeation rate 385.177 µg/(cm²*min). Closed-loop BDT 34.06 minutes, SBT 29.98 μg/cm2/min, SSPR 13.62 μg/cm2/min, CP 0.059, 356.73 and 1219.58 μg/cm2; permeation rate 10.597µg/(cm²*min). The use of gloves made of butyl rubber with Viton® and butyl rubber at PT. X is suitable for protecting workers to >30% glutaraldehyde, while a neoprene glove is not recommended.
