Document Level 2

Risk management measures applicable to HTIW

Introduction

The Level 2 documents deal with risk management measures. They cover generic practices and procedures that should be applied to limit exposure to fibrous dust in a range of situations and scenarios, linked principally to key activities (functional jobs) within the workplace.

At present, seven documents have been produced or are planned at this level, covering local exhaust ventilation, mixing and forming operations, finishing operations, modules, good housekeeping and hygiene, training, and use of personal protective equipment.

Monitoring methods for airborne fibres

This document focuses on monitoring methods for airborne fibres that can be used to establish if workplace controls are adequate and that worker exposure has been minimised. It is not intended to be used as a tool to carry out monitoring but as a guide to highlight key points of monitoring which should be considered when choosing a professional to carry out occupational hygiene monitoring.

Use of Personal Protective Equipment (PPE)

There are a number of situations in which it can be envisaged that there would be a need for PPE in addition to or instead of other control measures. This document details the various types of PPE and discusses different options, particularly in regard to respiratory protection. [Download file]

Training

This document describes the training needs for workers handling HTIW products and ways to organise and evaluate the training. [Download file]

Exposure reduction through use of alternative product forms and processes

This document provides information on potential means of reducing workplace exposure to HTIW dust by the use of alternative product forms and processes. The advice provided in this document is generic (i.e. it applies to all HTIW products). [Download file]

Finishing applications

Finishing is the preparation of HTIW products for installation or final use and can incorporate a number of activities, done both by hand (manual) and by machine (automated or semi-automated). These activities can involve high or low energy processes. [Download file]

Exposure to Fibrous Dust during Mixing / Forming

When wet formed parts are made, the initial mixing operation can generate elevated levels of airborne dust. This dust can be controlled in a number of ways, as summarised below.

Good Housekeeping and Handling Practises for HTIW

Dust is generated when products are handled or machined. In order to reduce the amount of airborne dust generated when handling HTIW based products, the following handling practices are recommended. [Download file]

Local Exhaust Ventilation (LEV) Systems for HTIW

LEV systems operate on the principle of capturing a contaminant at, or as close as possible to, the source of emission. The first consideration should always be to avoid generating emissions. If emissions cannot be avoided, LEV is the preferred method of control. [Download file]
