TOOLS (For the Practicing Industrial Hygienist)

The following software tools provide the practicing industrial hygienist with quick and easy access to the information necessary to evaluate exposure profiles and determine if the exposures are acceptable, not acceptable or if more data is needed to make the determination of acceptability. The tools are all free and are regularly updated. Several are available in multiple languages.

  •  Basic Exposure Assessment and Sampling Spreadsheet

  •  Functional Requirements for IH Systems​ provides basic and advanced requirements one may need in a computer database system to be able make informed exposure judgements. It is important to have a database tool that has the ability to incorporate qualitative and quantitative assessments.

  • IH MOD​ General Help

  • IHSTAT an Excel application that calculates a variety of exposure statistics, performs goodness of fit tests, and graphs exposure data. Multiple languages are available. The book, “A Strategy for Assessing and Managing Occupational Exposures” is intended to accompany this. The links below will show you how to adjust the macros settings in your version of Excel, if needed

  • IHSkinPerm​ is an Excel application for estimating dermal absorption. Basic knowledge of Excel is all that is needed to operate IH SkinPerm. IH SkinPerm is a work product of the AIHA Exposure Assessment Strategies Committee (EASC) and the Dermal Project Team (DPT) in collaboration with Wil ten Berg, author of the original SkinPerm model. Although various parameters and data outputs have been explained or defined in IH SkinPerm through comments tagged on individual fields, users are encouraged to read Chapter 13 of the Mathematical Models for Estimating Occupational Exposure to Chemicals, 2nd edition, AIHA Press, 2009, C. Keil Editor. This is a useful reference for understanding the science and terminology associated with skin permeation. Refer to the IH_SkinPerm_Manual_May_2017.pdfHelp Manual for any questions.

  • Industrial Hygiene Data Interpretation App is a game you can download on your smartphone or tablet PC. This game illustrates the need for industrial hygienists to use statistical tools every time they interpret sampling data. The IH DIG is a fun app to help Exposure Assessors train their unconscious data interpretation algorithms to better match a Bayesian Likelihood analysis. The App is fun but a serious look at exposure assessment decision making. Download here, For iPad, For iPhone, For Android

  • IHEST_V15.xlsmIH Exposure Scenario Tool (IHEST) guides the assessor through the process of collecting general information about the workplace, specific scenario and agents(s), providing cues for measuring or estimating the important determinants of exposure such as generation and ventilation rates. It also prompts the user to specify the type of engineering controls; this information is needed later when making initial judgments by applying the Qualitative Exposure Assessment Checklist (see below).

  • ChecklistV33.xlsmThe Qualitative Exposure Assessment Checklist (The Checklist) requires only four readily available pieces of information: The Occupational Exposure Limit (OEL); the Vapor Pressure of the pure chemical (VP) when the agent is gas or vapor form; the observed or reported worplace control measures (observed level of control) and the required level of workplace control (required level of control). It can be applied in just a few minutes using readily available information and has been shown to be significantly more accurate than subjective intuitive judgments. The user is referred to Chapter 6 of "A Strategy for Assessing and Managing Occupational Exposures", 4th Edition AIHA Press.


NIOSH

NIOSH Lifting Equation (08/2017) for iOS and Android: The NIOSH Lifting Equation calculator (NLE Calc) can be used to calculate the recommended weight limit (RWL) and lifting index (LI) for single or multiple lifting tasks. The LI is an index of the relative physical stress for performing a particular lifting task, while the composite LI or CLI is an index of the overall physical stress for performing multiple lifting tasks. NIOSH recommends an LI and CLI of 1 or less for protecting workers from physical stress related to development of low back disorders.

OSHA-NIOSH Heat Safety Tool (06/2017) for iOS and Android: Take precautions against outdoor heat while at work with the OSHA-NIOSH Heat Safety Tool. Featuring real-time heat index and hourly forecasts, specific to your location, as well as occupational safety and health recommendations from OSHA and NIOSH. The OSHA-NIOSH Heat Safety Tool is a useful resource for planning outdoor work activities.

NIOSH Pocket Guide (05/2017) download via mNPG: The NIOSH Pocket Guide to Chemical Hazards Mobile Web App (mNPG) informs workers, employers, and occupational health professionals about workplace chemicals and their hazards. The mNPG gives general industrial hygiene information for hundreds of chemicals/classes, presenting key data for chemicals or substance groupings (such as cyanides, fluorides, manganese compounds) that are found in workplaces. The app can be used offline when no internet or cell phone connection is available.

Homecare Safety (03/2017) for iOS and Android: The CDC/NIOSH Caring for Yourself While Caring for Others Homecare Safety app serves as an electronic resource for trainers in delivering a free online seven-module safety and health training for homecare workers. This tool includes: course preparation tips, lesson plans, supplies checklists, links to free course materials including slide presentations and participant handouts, and detailed delivery instructions for each of seven safety and health modules. Designed to be flexible, trainers may choose to deliver the entire seven modules of the curriculum or select individual modules to supplement existing training programs.

Sound Level Meter (1/2017) for iOS: The NIOSH Sound Level Meter (SLM) app can be used by safety and health professionals and industrial hygienists to assess risks, similar to how they would use a professional sound level meter, and by workers to make informed decisions about the potential hazards to their hearing in the workplace. The app allows the user to acquire and display real-time noise exposure data and help promote better hearing health and better prevention efforts. The app provides a readout of the sound levels using the built-in microphone (or preferably using an external, calibrated, microphone) and reports the instantaneous sound level in A, C, or Z weighted decibels. The app also contains some basic information about noise and hearing loss prevention. In addition, the app allows the user to save and share measurement data with others using the device communication and media features.

ine (04/2016) for Android: ErgoMine is an ergonomics auditing app for Android currently available in the Google Play store. This audit tool identifies ergonomics and safety deficiencies for three types of mining operations: (1) haul truck, (2) bagging, including small bag and intermediate bulk container filling and preparation for shipment, and (3) maintenance and repair in coal preparation and minerals processing plants. Unlike most ergonomic and safety audit programs, ErgoMine provides recommendations to address all deficiencies identified by the app. Mines can then implement these targeted recommendations to improve mineworker safety.

Ladder Safety (2013) for iOS and Android: The NIOSH Ladder Safety app is intended to assist portable ladder users with their ladder-related safety needs. The easy-to-use interactive ladder safety application features a multimodal indicator, which uses visual, sound, and vibration signals to assist the user in positioning a ladder at an optimal angle. Furthermore, the application provides graphic-oriented interactive reference materials, safety guidelines and checklists for extension and step ladders selection, inspection, accessorizing, and use.​
