Methodology for data providing
Methodology for data registration in the HazChem@Work database and recommendations for its use
Depending on whether you want to introduce data or to use it you may go to one of the two points bellow. It is however recommended that you read both before starting.
1. Data registration in the HazChem@Work database
The data registration uses a template containing 6 sections, each with various subsections, as presented below.
The data with an asterisk (those in section 1 and 6) are mandatory for all the other sections.
1. Chemical substances* THIS WHOLE FIELD IS MANDATORY
- Name – the chemical name will be the English e.g. CAS name, IUPAC, or other names commonly used for the chemical (e.g. the name used in the Annex of CLP Regulation or in the C&L Inventory published by ECHA which can be found on ECHA’s website).
- ID number (e.g. CAS, EC, Index)
2. Exposure and contextual data
- Kind of exposure (inhalation/dermal): Put „Yes“ for the type of exposure that has been measured. THIS FIELD IS MANDATORY
- Measurement method: THIS FIELD IS MANDATORY
Name: specify the abbreviated name of the method when standardised e.g. ISO 15202-1:2012; NIOSH Mercury 6009; the same for national standards.
Standardised: put “Yes” if it is a national or international standard and „No“ if is not.
- Exposure measurement (e.g. different values such as average, peak, minimum, percentiles, kind of exposure) THIS FIELD IS MANDATORY
Measurand (measured quantity or object) if different from the substance in section 1 ( e.g. for metabolites in biological samples)
Measurement conditions: specify type of measurement – personal sampling, static sampling, skin wipe sampling, fluorescence stain skin sample, other
Matrix – if the substance is measured in a special matrix (e.g. in blood) specify it in English.
Peak value : put the highest short-term/instantaneous measured value per shift
Average value: put the corresponding 15 minutes or 8 hours values, arithmetic mean, other
Value: use point to separate the decimals
Unit : specify the unit in a standardized way (mg/m3) ; use the same units as those specified by legislation in case of (B)OLEs
- Work process, kind of workplace, task, technology: specify briefly, in English
- Number of exposed workers (e.g. per substance/ task/ sector/ occupation/ country): put the number of workers if known at country level for all sectors, occupations etc, or at national level for a sector, or occupation or task. Information referring only to an individual workplace or company should not be registered.
- Duration and frequency of exposure: provide the total duration in minutes per shift and the frequency as number of occurrences per shift (N.B. the total duration may result from performing the operation several times per shift, each time having a different duration).
- Risk management measures (e.g. PPE, exposure monitoring, substitution) put „Yes“ or “No”, for individual cases not for bigger groups (e.g. sector, country).
3. Production and use of chemicals at national and European level
- Production: put the value in tonnes per year and specify the year in section 6
- Consumption: put the value in tonnes per year and specify the year in section 6. If it refers to a sector add the sector code in section 6.
- Uses: specify process category (PROC), product category (PC) or article category (AC) as in REACH.
4. Disease data and adverse effects
- Type of diseases (e.g. occupational diseases, cancer, adverse effects): recommendation to use the ICD 10 codes -International Classification of Diseases elaborated by WHO
- Contextual data (e.g. work history, workplace conditions, exposure to chemicals)
- Sector, occupation: put corresponding data in section 5 (see below).
- Type of workers:
– for individual cases put age, gender (M or F), qualification, new workers („Yes“/“No“) , maintenance workers („Yes“/“No“), pregnant or breastfeeding workers (“Yes”/“No“), young workers (16-18 years, “Yes”/“No“)
– for group statistics- put related figures, or percentages whenever available.
5. Sector and occupation data
- Categorisation for sector*: use NACE codes (at least two digit level e.g. C10.1) THIS FIELD IS MANDATORY FOR SECTION 2, 3 and 4.
- Company size: choose one of the following: micro for less than 10 employees, small for less than 50, medium for less than 250, large for more than 250 employees
- Categorisation for occupation*: use ESCO, ISCO 08 code THIS FILED IS MANDATORY FOR SECTION 2
6. General information * THIS WHOLE FIELD IS MANDATORY
- Procedure of data collection: for measurements specify if it is – a compliance check, a post accident/incident inspection, preventive monitoring, national campaign
- Name of database: provide the name of the database in English and its abbreviation in the original language
- Owner of the data source: provide the full name of the owner
- Year of collection: provide the year when the data was generated
- Country: provide the name of the country in English
