FOCAL JMLab, a stock company incorporated under the laws of France and registered with the trade and companies registered of Saint-Etienne under number 344 394 309 000 35, having its registered office at 108 rue de l’avenir, 42350 La Talaudière, France.
The speakers concerned by this manual use a pure Beryllium inverted dome tweeter system, capable to extend the bandwidth up to 40Khz.
Regarding the potential hazardousness of Beryllium, a raw material constituting the tweeter, some instructions (defined hereunder) must be respected by the user of these speakers in order to prevent any risk of absorption of said material.
Nevertheless, in solid form and based on the current state of knowledge at the date of printing of this precautionary manual, the risks are limited, being specified that the hazardousness of the Beryllium mainly results from its inhalation, ingestion or contact in vapour form or microparticles.
Characteristics of Beryllium
| Carcinogenicity Category 1B | H350 i: May cause cancer when inhaled |

| Acute toxicity – Category 3 | H301: Toxic if swallowed |
| Specific target organ toxicity, repeated exposure – Category 1 | H372: Causes damage to organs through prolonged or repeated exposure |
| Serious eye damage / Eye irritation – Category 2 | H319: Causes serious eye irritation |
| Specific target organ toxicity (single exposure) – Category 3 | H335: May cause respiratory irritation |
| Skin corrosion / irritation – Category 2 | H315: Causes skin irritation |
| Skin sensitivity – Category 1 | H317: May cause an allergic skin reaction |
Precautions of use
It is essential to scrupulously respect the following precautionary measures.
|
The Beryllium dome should never be in contact with abrasive material
Beryllium is a stable product at room temperature. Nevertheless, it reacts with the following acids: sulphuric, hydrochloric, and hydrofluoric (with hydrogen release).
Conditions to avoid: heat, sparks, open flame, or any other sources of ignition. Beryllium is incompatible with oxidizing agents, and also notably bromine pentafluoride and performic acids. It explodes when heated with magnesium.
In finely divided form, Beryllium is a moderately flammable product. In a contained space, dust cloud of the metal may explode in the presence of a source of ignition. In case of fire, Beryllium releases highly toxic smoke and vapour.
In case of fire, the recommended fire extinguishing agents are engineered powders for combustible metals or, failing that, other inert powders. It is also recommended to wear adequate personal protective equipment to prevent contact with the substance orits products of combustion as well as full self-contained breathing apparatus.
- Generally, prevent skin or eye contact, ingestion or inhalation of all or part of the Beryllium dome. The manufacturer underlines the fact that its absorption by inhalation, dermal route or ingestion can cause severe physical afflictions.
In the event of damage to the dome
In the case that the Beryllium dome is damaged in whatever form, its whole surface should be covered over. In such case, it is recommended to contact your retailer in order to dismantle and replace the tweeter by the relevant department of the distributor.
If the dome is broken, particles of Beryllium must be carefully recovered and placed in a sealed plastic bag. It should be returned to the retailer at the same time as the speakers.
First aid
If inhaled: in case of inhalation of smoke or dust of Beryllium, bring the person outside or to a ventilated area and put the body into a half-sitting position so that the person can breathe comfortably. If not breathing, give artificial respiration. Take the person to the nearest medical emergency treatment centre or call a poison control centre.
In case of contact with eyes: flush immediately and bathe the eyes with water for 15 minutes or until removal of the product. Remove contact lenses if present and if it is easy to remove them. It is recommended to see a doctor.
In case of contact with skin: immediately remove contaminated clothing and shoes. Throw away clothing and shoes. Wash the skin with soap and water for at least 15 minutes. Immediately and carefully clean the cuts and wounds. Any particles of Beryllium which stick under the skin must be removed. See a doctor
If swallowed: if victim is conscious and alert, rinse mouth with water and give some water to dilute. Seek immediate medical assistance. Never give any liquid if the victim is unconscious or convulsing. Vomiting should only be provoked by a doctor or poison control center’s order. See a doctor immediately.
