This paper describes a study aimed at characterizing the exposure to physical and chemical by-products from the deployment of airbag restraint systems.
DESIGN, MATERIALS AND METHODS: Specifically, the levels of particulates and the composition of gases and bag fabric speed were measured in the passenger compartment following deployment of either a driver's side or driver's side/passenger's side airbag system.
A Fourier transform infrared analyzer (FTIR) and chemiluminescence analyzers were used for gas analysis, a cascade impactor and gravimetric filter measurements for aerosol determination and high-speed films to determine fabric speed.
The measured gases were found to be within the recommended guidelines for human exposures, but no guidelines exist for particle exposures of this magnitude (150-220 mg/m3) but short duration. High-speed films were also taken of the deployments to obtain an estimate of the fabric speed as it leaves the module. The maximum average speed for both types of airbag was approximately 100 mph and in both cases average speeds ranged from lows near 50 mph to highs of over 200 mph.
本文描述了一项旨在表征安全气囊约束系统展开时物理和化学副产物暴露情况的研究。
设计、材料与方法：具体而言，在驾驶员侧或驾驶员侧/乘客侧安全气囊系统展开后，测量乘客舱内的颗粒物水平、气体成分和气囊织物速度。
使用傅里叶变换红外分析仪（FTIR）和化学发光分析仪进行气体分析，使用级联冲击器和重量过滤器测量气溶胶，并使用高速胶片确定织物速度。
所测气体被发现符合人体暴露的推荐指导标准，但对于这种量级（150 - 220毫克/立方米）但持续时间短的颗粒物暴露，尚无指导标准。还对展开过程拍摄了高速胶片，以估算织物离开模块时的速度。两种类型安全气囊的最大平均速度约为每小时100英里，且在两种情况下，平均速度范围从接近每小时50英里的低值到超过每小时200英里的高值。
