Safety
Special on COVID-19
- We ask you not to enter if you have or feel flu syntoms (fever, chills cougth, sore throat, stuffy nose, muscle aches...) or you have been in contact with people displaying flu syntoms in the last 15 days.
- In presence of health conditions that make them susceptible to particular and more serious consequences in case of contagion, we advise to perform the experiment via sample mailing (remote operation).
- Promptly notify the beamline scientists (who will notify the persons in charge) of the onset in the workplace flu-like symptoms taking care to remain at an adequate distance from people possibly present.
In accordance with general rules for the COVID-19 containment, all workers operating at the beamline must observe to the following rules:
- Maintain a safe distance of at least 1m and minimize contact with other persons.
- Coordinate work in order to reduce contact times. Split the work into shifts or into separate days whenever possible.
- Always carry a surgical-type mask with you and wear it covering mouth and nose whenever a distance of at least 1 m cannot be maintained.
- A maximum number of two persons (including, when authorized, external users) may work at each beamline experimental station and in ventilated rooms (experimental hutches, laboratories) without masks as long as a distance of at least 1m can be maintained. Whenever more than two people are needed to perform an experiment, a preliminary authorization should be obtained from the group coordinators.
-
Masks must not be shared. Used surgical-type masks must be discarded in the dedicated bins. Information on bin locations can be found here.
- As you enter wash hands with soap following the established rules (at least 20 s). Wash hands regularly with soap or hand sanitizer dispensers, which can be found on site. Avoid touching eyes, mouth and nose with your hands. Avoid shaking hands and hugs.
- Hands have to be cleaned each time before using shared equipment. The equipment shared by multiple persons (e.g. handles, phone, all keyboards of instruments and PCs, mouses, monitors, tables, pens,....) has to be cleaned with disinfectants before and after each use. All tools (screwdrivers, pliers, scissors,...) have to be cleaned with ethanol in the ultrasound machine.

Work places
A maximum presence of two people is allowed. There are three separate work stations marked with tape (hutch, branch C, monochromator). Only 1 person can work in the space delimited by the yellow and black tape on the floor. See the photos. Only 1 person is allowed inside the acquisition hutch. Do not enter inside the hutch if a person is already inside.The door of the hutch has to remain open and the airconditioner always OFF.
Only one person can work inside the LASER HUTCH. Even when working alone, surgical-type masks must be always weared inside the laser hutch.

Safety and General Rules at the BACH beamline
Before starting any experimental activity at the BACH beamline, there are two types of training required:
1. General safety training required by Elettra in order to access the Experimental Hall (Emergency plan, Radiological risk, Radiation Protection Activity, Elettra Safety Training, COVID-19 rules)
2. Beamline Specific Orientation (by reading this document carefully before starting your experiments and reading the BACH manual online: http://www.elettra.trieste.it/lightsources/elettra/elettra-beamlines/bach/bach-manual.html)
In case of emergency (water flooding/fire...) call the BACH beamline scientists (numbers posted on the wall inside the data acquisition hutch) and the Control Room: 8922/8923.
Your first priority should be to secure your own safety. Before starting your experiments, please note the locations of emergency exits, fire extinguishers and fire alarms.
Always follow the three-point rule to avoid falls and electric and Chemical/Gas safety rules.
Working alone is strongly NOT recommended! In particular, lone working on the platforms and around the BACH endstations must be avoided. Any activity at endstations and beamline (outside the data acquisition hutch) should not be carried out unless a second person is standing by or the user has been authorized by BACH staff to carry out special procedures. Any risky situation must be avoided.
Please also remember that many experimentalists are working together in the experimental halls in a common space: always consider the safety of the others!
Situations of potential danger should be reported right away to the BACH beamline scientists. Communicate any accident or irregularities to the beamline staff immediately. Malfunction or damage of the equipment should be reported right away to the BACH beamline scientists.
No food is allowed at the BACH beamline. Do not eat at the BACH beamline are (endstations and BACH hutches). In the Building T ground floor there is a kitchen for storage of food and drinks and for having your meal. Inside the Experimental Hall there are water distributors for drinking.
Never bring with you the key of the door of the data acquisition hutch.
If you need to leave the beamline unattended, make sure that the water cooling of the evaporators has been switched off, the superconducting magnetic field is zero.
The users must keep careful notes of all research engagements on the official BACH logbook. The BACH beamline logbook MUST be used to record all BACH beamline activity and to report all equipment/software/controls malfunction or damage (besides sending right away an email to the BACH beamline scientists).
Users practice safe and responsible computing. Please do not use internet on control computer. Never install software on any BACH computer.

Risk of stumbling or falling from stairs, platforms: Three Point Rule
The biggest cause of falls is human error and failure to follow the Three-Point Rule. □ I have read and accept Safety Guide for using High-Pressure Gas Cylinders
When you need to use gas cylinders of He, please ask the beamline staff. When authorized, use the proper carriage to transport high-pressure cylinders. □ I have read and accept Other Experimental Hazards
Avoid contact with electrical heat tape during bake out (can cause burns)
Avoid contact with Ion Gauges (can cause burns to the skin)
Place blades, tips, needles in a container with appropriate label (chem cabinet outside the PC hutch) □ I have read and accept |
Electrical Safety
The most serious accidents caused by electricity are electric shocks and fires caused by overheating. The followings are safety measures to avoid electrical accidents. Do not use excessive branching and wound cord reels. They might cause overheating, and damage to or burning of cables. Before using any electrical cable or plug and power supply, follow the instructions of the beamline scientists.
□ I have read and accept Cryogenic liquids and dewars
Unless explicitly authorized, users are not allowed to handle cryogenic liquids and dewars. They have always to ask beamline staff and be trained. Lasers
Laser can be occasionally used at this beamline. Everyone who uses a laser should be aware of the risks. |
Chemicals and Nanoparticles
Consider all chemical reagents hazardous and consult the Chemical Products Information Sheet (MSDS); Before manipulating a chemical reagent carefully read the instructions and information shown on the product label; Take to the experimental stations (beamlines) only what is necessary for the carrying out of experiments and strictly according to the descriptions shown in the Samples Safety Sheet associated to the proposal;
The Safety Data Sheets of the Chemicals available for the BACH beamline users can be found here: Download Safety Data Sheets. The paper version of these Data Sheets can be found inside the BACH hutch (blu ring binder).
We do not accept pyrophoric (e.g. silane, borane, and phosphine etc.) or highly unstable gases (i.e., 1,3-butadiene, methyl acetylene, vinyl chloride, tetrafluoroethylene, and vinyl fluoride, etc.) gases. Furthermore, any corrosive, inflammable, highly toxic or dangerous gas or gas mixture (including H2S, NO, NO2, ..) is not accepted at this beamline. Only gases available in lecture bottles/minican can be used (upon request).
Be aware of the hazardous properties of dry Nanoparticles. Nanoparticles are able to pass through cell membranes in organisms and may interact with biological systems. The manipulation on the beamline and related laboratory of nanoparticles (<2.5 micron) in powder form is strictly forbidden. Measurements on nanosized materials can be authorized only when the sample is firmly bonded to/inside a substrate or in a sealed confinement. In any case hazardous materials producing toxic or contaminant matter suspensions on air are stricly forbidden.
Handle nanoparticles in suspension in a fume hood, externally ducted biological safety cabinet, or glove box. Regularly laundered lab coats must be worn. Arm sleeves are required where high levels of exposure or splashes of solutions containing nano particles are anticipated. Gloves (disposable nitrile) must be worn when handling nano materials. Clothing should include long pants and closed toed shoes. Nanoparticle solutions need to be handled over disposable bench covers. All solutions and solid materials must be disposed of as hazardous waste.
Manipulate toxic samples and solvents only in the Fume Hoods/exhauster cabins (available on request at user support Lab), NEVER at the BACH beamline. If it is necessary to take volatile solvents to the beamline, they should be placed in a small sealed bottle with appropriate labels;
Perform hazardous reactions only in the exhauster cabins, on small scales and only if authorized by the Elettra safety group and head of user Chemistry support Lab;
Locate the fire extinguishers and in case of doubts ask for the advice of the securities section;
Manipulate all chemical reagents with nitrile gloves;
Do not answer the telephone or touch door handles, equipment, face and hair with contaminated gloves. Do not transit from one place to another wearing contaminated gloves.
Before preparing solutions and samples verify the chemical compatibility between the reagents;
Label the residues and any sample and/or prepared solution (description of contents, the responsible name and the beamline).
