Known Hazards

The fine dust produced in machining operations may cause irritation of the skin or bronchial asthma and rhinitis after inhalation; a well-functioning dust extractor fan is recommended. The substance responsible for the allergic reaction is probably the naphthoquinone desoxylapachol[

The height of the tree at the moment of first flowering is important in silviculture. When it is long (it may reach up to 10 metres), the final bole form is positively affected, but early-flowering trees may develop extremely wide crowns and short boles. This characteristic is clearly undesirable in timber-crop species and warrants strong selection against flowering in conjunction with increased effort to develop commercial methods of vegetative propagation. The time of the 1st inflorescence is determined by both genetic and environmental factors[

The heartwood is often dull yellowish when freshly cut but turns golden brown or sometimes dark greyish-brown after exposure, often streaked grey or black; it is distinctly demarcated from the up to 50mm thick band of yellowish-white or pale yellowish-brown sapwood. The grain is straight, wavy or slightly interlocked, with a rather coarse and uneven texture, growth rings are distinct. The wood is oily to the touch and when freshly cut has a smell reminiscent of leather. The wood is a medium weight timber that is rather soft, it is durable to very durable, with an average service life in contact with the ground of more than 10 years under tropical conditions and more than 25 years under temperate conditions. It dries well but rather slowly, rates of shrinkage are low, once dry it is very stable in service. It is not difficult to work, but requires some effort, mainly because of the presence of silica (up to 1.5%); stellite-tipped saws and tools tipped with tungsten carbide are indispensable for sawing and planing operations; it is difficult to chisel with a hollow square mortiser, but turns well; nail and screw-holding capacities are good, but pre-boring is recommended to avoid splitting; gluing is only successful on freshly machined or newly sanded surfaces. The wood bending properties are moderate; there is a tendency to buckle, and the wood is only suitable for bends of moderate curvature; painting, staining and polishing require freshly machined surfaces or a pretreatment with thinner, however it can be varnished and polished beautifully. Being classified as very resistant to teredo activity, the wood is an excellent timber for bridge building and other construction in contact with water such as docks, quays, piers and floodgates in fresh water. In house building, teakwood is particularly suitable for interior and exterior joinery (windows, solid panel doors and framing) and is used for floors exposed to light to moderate pedestrian traffic. It is also used quite extensively for garden furniture. Other uses are for building poles, transmission line poles, fence posts, wallboards, beams, woodwork, boxes, musical instruments, toys, railway sleepers and railcar construction[
