Basic Chemical Safety

This part is for all personnel that requires access to the A-D buildings.

The objective of the basic chemical safety training is to give you enough information on how to identify chemical hazardous areas and were they exist around the facility. Personnel that will bring chemical hazards to the facility or engage in hazardous chemical work also need to complete the extended chemical safety training.

1. Applicable Regulations, Provisions and Abbreviations

CLP (European regulation nr 1272/2008, link to a guide not the law)

AFS 2014:43 – Chemical Hazards in the Working Environment

AFS 1999:7 – First aid and crisis support

AFS 2007:5 – Pregnant and nursing employees (only in Swedish)

AFS 2008:13 – Signals and signs (only in Swedish)

GHS: Globally Harmonized System of classification and labelling of chemicals

SAM: Systematic Work Environment Management

CS: Chemical Safety

2. Responsibilities

The director has the main responsibility that the facility complies with all laws and that regulations are followed. Work is current underway to clarify delegations from the director to other parts of the organization. When this work is complete the SAM -responsible for each work area will be responsible to ensure that required documentation is established and maintained regarding chemical hazards (e.g. risk assessments and work instructions).

The role of the CS team is to support the organization in this work to comply with all chemical regulations.

2.1 MAX IV Staff

All MAX IV employees have a personal responsibility to follow rules, guidelines and work instructions posted. To gain access to the A-D building personnel need to know which areas at the facility permanent hazards exist, basic rules and how to act in the case of an emergency.

All personnel working with chemicals have to take the extended chemical safety training and the responsibility to inform themselves of the documented working rules located in respective area and conditions that apply for working with hazardous chemicals.

2.2 External Users

External users must declare all chemicals they intend to bring to the facility during the proposal phase in DUO. To accepted proposals, last minute changes (4 weeks before) are only possible if the experiment is within the same hazard classification (e.g. changing inert gas to a flammable or toxic gas would change the hazard classification of the experiment). The local contact or beamline manager shall involve the CS team early on if plans like this are in motion. If the user have brought chemicals or samples that have not been declared upon arrival, the local contact must contact the CS team for approval. Safety for users can be found here.

2.3 External Contractors

The person at MAX IV who is responsible for hiring external contractors is called local contact and this person is responsible for the external contractors during their stay at MAX IV. Local contact must register the external contractor here. Local contact must ask the external contractor if they intend to perform any hazardous work involving chemicals. If so, the local contact must and also inform the contractor to contact the CS team. The external contractor will be prompted to fill in a form where they explain their planed work. Contractors are not allowed to start any hazardous chemical work at MAX IV before the form is approved by the CS team. The work decision will be sent to the contractor and the local contact at MAX IV who checks what actions must be taken from MAX IV to prevent any hazards for staff.

2.4 Study Visits and Guests

Study visits groups and guests must be informed by the guide of local rules were appropriate. The guide is responsible for acquiring information on specific day-to-day hazards at the facility and plan any tour accordingly.

3. Chemical Hazards

The term chemical hazard includes both hazardous chemical substances and mixtures when they occur as a chemical product and in other manners. Other manners may be as exhaust fumes or other air pollution, or in or on a material, plant or technical device.

Observe that substances which are not classified as hazardous according to CLP and thus do not require hazard pictograms (part 3.1.1), may still become dangerous under certain conditions. This means that a hazard may be generated when an otherwise “non-dangerous” substance as aluminium is used e.g. acid spill on aluminium foil generates hydrogen gas which is a fire and explosive hazard.

3.1 Chemical Hazard Labelling

Since 1 June 2015 all newly produced chemicals on the European market are classified and labelled according to CLP. Old containers are allowed with the old labelling (In Sweden, the orange/black pictograms) until 1 June 2019. If a product with the old labelling is transferred to a new container it must be re-labelled according to GHS. A complete overview of the classification and labelling can be found here. Below is an example of a GHS label usually found on chemical products.


3.1.1 Pictograms

The GHS hazard pictograms consist of 9 pictograms and are shown below. Substances marked with any of these pictograms are classified as dangerous substances.


3.1.2 Signal Words

Signal words is a new implementation of GHS and indicates the level of severity. The signal words Danger and Warning are assigned to a specific hazard category where Danger is indicating a more severe hazard category. Some of the lower hazard categories may not be assigned a signal word. Signal words are present directly on the label for chemical products.

3.1.3 Hazard Statements (H and EUH)

The hazard statement (H) is assigned to each hazard class and category. The GHS consists of three hazard groups: physical, health and environmental. Each group has multiple hazard classes, further containing categories and sub categories. EU have added a few extra hazard statements labelled as EUH. You can find all H statements here.

3.1.4 Precautionary Statements (P)

Precautionary statements (P) are replacing the old S-phrases and they function as a set of standardized precautionary phrases giving advice about the correct handling of hazardous chemicals. You can find all P statements here.

3.1.4 Safety Data Sheets (SDS)

Safety data sheets are available for all substances on the market as regulated by CLP. These are available from the supplier upon request or usually easy accessible through their webpage. The SDS is needed to make a proper risk assessment. Examples of SDS are shown below (click to enlarge).


3.2 Areas at the Facility with Permanent Hazards

The listed areas below are larger areas were dangerous substances will be present at all times and extra caution is advised. Signs with pictograms shall be present if any chemical hazards are present.

Open areas in A-, B-, C. and D-buildings

1. Gas bottles.
Gasbottles may be present at all areas in the building and shall be marked by a tag from the CS team. The tag implies that the bottle have been acquired from the gas depot correctly and the work area is known. Gas bottles not in use shall be stored outside in the gas depot or inside the designated 90 min fireproof gas cabinets where approved by the CS team. It is not allowed to pick-up gas bottles from the central storage without approval. Routines on how gas bottles will be handled is currently underway.

2. Truck charging stations.
Charging stations for trucks are spread out around the A- and D-buildings. They must be clearly marked and necessary protective equipment must be present at those areas.

3. Spray cans and ethanol/acetone in 0.5 L bottles.
These chemical products are extremely flammable solvents or gas under pressure. All solvents in 0.5 L squeeze bottles must bear a tag from the CS team due to the required tracking of flammables in each fire cell. Please observe any EX-classed area (marked with a yellow/black EX sign)

Chemical laboratories (A- and D-buildings)

There are in total four chemical laboratories that will be available for staff and users. Access to the chemical labs requires the extended chemical safety and a Lab-Access training (currently under construction). Contact the CS team for more information.

The chemical safety laboratory located between the A- and the D-building will serve as the main contact point for staff and users with the CS team. Staff chemicals will be stored in this laboratory along with consumables, ethanol, acetone and mini-gas bottles.

Beamlines/STM lab (A-, C- and D-buildings)

During commissioning and operation every beamline possess different chemical hazards. Note that the chemical hazards at a beamline can change several times a week. Please observe the safety information that should be located outside the control room and posted by the beamline manager. Never enter a preparation lab or experiment area before contacting a beamline staff member.

Workshop area/vacuum laboratory (D-building)

The machines inside the workshop use different oils and cutting fluids. Ethanol, detergents, gas bottles, spray cans are other chemical hazards in that area. A temporary storage room for dangerous substances exists in the workshop. Always contact a workshop staff member before entering the workshop area.

Storage area (outside D-building)

The main gas depot is placed here and all dangerous waste will be stored here until it is collected. Staff will have limited access to this area.

4. Miscellaneous Information

4.1 Food and Beverages

Consumption of any food and beverages is strictly forbidden in areas were chemical hazards are present.

4.2 Pregnant and Nursing Women

If you are pregnant or nursing, contact your line manager who is responsible to perform a risk assessment. If you are in the early pregnancy phase and afraid of being exposed to dangerous substances, you can contact the CS team in confidence for any questions.
