Assess workplace risks with the EMKG method

Run a structured risk assessment for inhalation, skin, eye, fire, and storage hazards using the EMKG control banding approach.

The EMKG wizard guides you through a risk assessment for a specific product. It determines the required control level based on the product's hazard group, the quantity used, and how the product is released into the workplace. Control levels range from basic hygiene practices up to fully enclosed systems.

EMKG stands for Einfaches Maßnahmenkonzept Gefahrstoffe, the Easy-to-use Workplace Control Scheme for Hazardous Substances, developed by BAuA.

EMKG wizard showing Step 1: Product Classification

Start an assessment

Open any product from your library, then select the EMKG tab. The wizard has four steps.

Step 1: Classify the product

Select whether the product is a Substance (pure chemical) or Mixture (formulation with multiple components). Then select the Physical State: Solid (powders, granules, pellets) or Liquid (solutions, emulsions, suspensions). NextSDS pre-selects these where the SDS data makes it clear.

Step 2: Select exposure routes

Choose which exposure pathways to assess. Each route shows the product's hazard group on a colour-coded scale (A = lowest risk, E = highest):

EMKG Step 2: selecting exposure routes with hazard group indicators

RouteWhat it assesses
Inhalation ExposureBreathing in vapours, dusts, or aerosols (groups A–E)
Skin/Dermal ExposureSkin contact and absorption (groups HA–HE)
Eye ExposureEye contact and irritation (groups Au-A–Au-C)
Fire & Explosives HazardFlammability and explosion risk (groups pc-A–pc-E)
Storage HazardHazards during storage (groups La-A–La-F)

Select at least one route to continue.

Step 3: Answer assessment questions

For each selected route, answer questions about how the product is used in your workplace.

EMKG Step 3: Risk Assessment questions for inhalation exposure

Inhalation

  1. Occupational Exposure Limit (OEL): whether an established exposure limit exists. If yes, select the OEL range (in mg/m³ for solids or ppm for liquids) to determine the hazard group directly.
  2. Quantity Group: the amount used per operation: small (millilitres/grams), medium (litres/kilograms), or large (cubic metres/tonnes).
  3. Application Method (liquids only): whether the product is sprayed. Spraying automatically sets the release group to high.
  4. Product Dilution (liquids only, when not sprayed): whether the product is diluted with water. Dilution automatically sets the release group to low.
  5. Release Group: how easily the substance becomes airborne, based on vapour pressure or dust generation. Low (boiling point above 150 °C), medium (50–150 °C), or high (below 50 °C).

Skin

  1. Effective Area: small (only a few splashes) or large (hands or forearms). Do not account for protective equipment.
  2. Duration of Skin Contact: short (under 15 minutes per day) or long (over 15 minutes per day). Repeated contact is added over the full day.

Eyes and Fire & Explosives

Both routes ask two questions:

  1. Release Group: low, medium, or high, with descriptions adjusted for solids or liquids.
  2. Quantity Group: small, medium, or large.

Storage

  1. Storage Quantity: under 50 kg, up to 200 kg, up to 1 000 kg, or over 1 000 kg.

Step 4: Review results

The wizard calculates a control level for each exposure route:

Control levelWhat it means
Level 1: MinimumGood hygiene practices, general ventilation, and basic PPE
Level 2: TechnicalEngineering controls such as local exhaust ventilation, enclosed transfer systems, respiratory protection, and monitoring
Level 3: ClosedFully enclosed systems, automated handling, supplied-air protection, continuous monitoring, and work permits
ExpertThe assessment exceeds standard control banding. Consult an occupational hygienist or certified specialist

Assessment results showing hazard groups and control levels

The results page shows a product information summary, an EMKG Hazard Groups overview with colour-coded scales for all five routes, and detailed recommendations for each assessed route.

Save the assessment

Select Save Assessment to store the results and add the product to a location's inventory. In the pop-up window, choose the workplace location from the list, then confirm. The assessment will be linked to that location for future reference.

Export as PDF

Select Export PDF to download a printable report of the full assessment, including all inputs, hazard groups, and control recommendations.

What to do next

For the highest-risk substances, run an ECETOC TRA exposure simulation to model predicted inhalation and dermal exposure against occupational exposure limits. This is particularly useful where you need to demonstrate that exposure stays within limits.
